OK, Mr_N_Derman's explanation and examples set me straight. I had read that section of the Wiki before but it never sank in.
What that means is that a farm with 18 x 18 spawn floors needs to have at least 2 village pods with at least 1 villager in each of them but 4 pods with villagers on each side is probably safest.
Note that with 18 x 18 spawn floors the actual size of the farm is, at least 20 x 20 before the pods are added.
Oh, and on the subject of only providing 3 meters between solid floors, that will reduce the farm output considerably.
When the Golem spawn routine selects a candidate as a possible spawn location in does so using floating point math meaning that the spawn point can be ANYWHERE inside the spawn block.
In the horizontal dimensions (X and Z) that means it's possible for a point 7.999 meters from the village center to be selected.
Since this point defines the center of the spawned Golem this means that half of that 1.4 blocks (.7 meters) will be hanging over an adjacent block (in the east/west axis) and about .5 meters in in the north/south axis. Note that Golems (actually all mobs and players, I think) always spawn facing south. Because of this "over hang" a extra block is required on each side of the floor to allow full access to all spawn locations.
In the case of the Y axis a point could be selected right at the upper limit of the candidate block putting the top of the Golems head at very close to 3.7 meters above the spawn floor which means no Golem will spawn if the gap is 3 meters.
Having a 3 block gap between floors would limit the possible spawn locations of that spawn area to less than 50% of maximum.
All this means that optimally spawn floors need to be 18 x 18 with a 4 block gap between the lower floor and the blocks making up the upper floor and if the upper spawn area is to be covered over the same 4 block gap is needed.

If you aren't part of the solution, then you obviously weren't properly dissolved.
What you say makes sense, though I've never seen anything about mobs spawning at non integer y values.
But I've let a iron farm with 3 block high ceilings run for 5 hours or so with no golems spawning.
When I removed the upper roof and left it for an hour I returned to this, I may have overdone the villagers a bit.
It's not that they spawn at non-integer heights, it's that the routine that looks for a suitable spawn location will pick a random floating point Y value within the 6 meter vertical zone and check if there's enough room for a Golem to spawn. I suspect that if the Y value were rounded down to the upper surface of the solid block below before checking for height restrictions that Golems could/would spawn in the 3 meter high space.
I'm surprised that you didn't get ANY to spawn in 5 hours.
Did you change anything else besides removing the ceiling?

No, just my position and just to check if golems needed the 24 block distance from a player I afk'd on that glowstone block in the middle of the picture, which obviously didn't stop them spawning.
I put the roof back on and AFK'd overnight (10 hours), not a golem.
Then I lowered the bottom floor (just in case removing the roof had been affecting the doors) and within 20 minutes I had 2 golems on the bottom floor (which was now bedrock.)
I created a new superflat world to do a test build of an iron farm with 18 x 18 spawn floors yesterday and got the upper floor finished and working this morning (it's 0135 here).
Also I shortened the drop shaft to prove it's possible to build the farm closer to the ground.
I started out building the farm at the standard 10 meter height above ground specified in the NIMS video.
Here's two shots of how I arranged the hoppers and 4 double chests.
One is of the actual farm with a sand stairway beside it to show how much the farm can be lowered.
However, if that were done you would have to walk around the base to get to all the chests.
As it is now I can stand in one spot and access all chests.
The second image is of an even tighter drop shaft. Since signs can be placed on glass blocks (they don't have to be glass but I like to see what's going on) the lave COULD be placed just 1 block above the hoppers.
It's not easy to see but there are two levels of glass blocks in that image.
You can save a little glass by using glass panes instead of blocks.
That would take care of the errant villager or mob that somehow gets into the drop shaft.

BTW - My NIMS style iron farm has a few embellishments because I like to check on things every once in a while.
Everything is made of things that mobs can't spawn on, half slabs, stairs, glass blocks, etc.
To be able to get to all four villager pods there is a half slab walkway all the way around the farm and the 4 upper corner blocks have been removed from the lower spawn floor's walls to provide four observation points. Half slab stairs are used to get to them (I could have used ladders).
There is a stone brick stairway from ground level up to the walkway.
I'm currently running a test to get an average yield per hour value for this design.

(Compared to my 16 x 16 version.)
At this time it has 40 doors and 24 villagers.
If you're gonna have a farm with more than 20 doors villagers, i recommend you build it with 19x19 pads with a 3x3 drop shaft, as having the golem spawn cap at two means you can get a second golem spawn whilst the first is in transit, and if they spawn on the same pad and reach the drop chute simultaneously, they can prevent each other from dropping down the chute, effectively blocking the farm up. This may sound like a rare occurence, but i've had it happen a few times. If your farm is in the spawn chunks and constantly running, you wouldnt want to turn up one day expecting shed loads of iron, and instead find its suffered that fate.

It's the number of villagers that determines the spawn cap isn't it?
1 golem per 10 villagers.
I think the only reason to have more than 21 doors would be if one wanted the villagers to breed naturally (without an infinite breeder.)

Where did you find information on a Golem spawn cap? I searched and didn't find anything.
I've run my farm for about 8.6 hours and got 342 ingots for a yield of 39.6 per hour.
That's with 21 villagers.
That's a 7% increase over my 16 x 16 farm which averaged 36.8 per hour.
I don't know if it's worth the effort.
Placement of the water sources to get no dead spots on the spawn floors was a serious pain.
I've increased the population to 43 villagers and will let it run for another 8 hours or so.
BTW - I've yet to see the 2 x 2 hole get stopped up.

Wow. Got way more response than I expected. Thanks to all for the great information. Another question, occasionally I will find a golem on top of the glass on the upper platform. I'm not sure how it gets up there since it shouldn't be able to spawn there and afaik golems can't jump. Would I be better off lining the top with half slabs instead, or maybe slabs and glass?

How high is your top wall?
Golems can step up on a 1 meter block without jumping.
Glass works just fine to prevent anything from spawning.
If your farm spawn floors are a minimum of 16 x 16 and the doors are symmetrically placed so that the village center is in the middle of the hole then the golems can't spawn on the walls because the walls are outside of the spawn zone.

If you aren't part of the solution, then you obviously weren't properly dissolved.
By the way, the trick to get water to flow to the center 2x2 hole with an 18x18 floor and NOT have any dead spots where Golems (and other objects) can get stuck is to place a ring of water sources around the inside of the entire upper layer of blocks of the three high block walls.
That's a total of 68 water sources for each spawning floor. SIGH!
Like this: S = water source, W = wall block, F = floor block, H = hole, _ = don't care.

_ FFFFFFFFHH
Below are screenshots of my, probably, final design of the 18 x 18 farm.
The first shows the lower spawn floor and you can see (at least on the near side) that the water sources are at the top of the walls.
The second shows the upper spawn floor which has glass blocks for the topmost wall layer so mobs can't spawn on it.
The third I just threw in to show the door placement.
Note: the reason the the lower spawning level walls aren't glass is that you can't place doors on glass. They have to be placed on solid blocks.

It sounds like your upper floor might be too low, that would allow golems to spawn on top of the wall (inside the glass on top).
Half slabs are no better than glass, both are considered transparent and allow the golems to spawn in them, just like the water on the spawning platform. And if they spawn with their feet in a glass block they can then step up on top of it
Making the wall higher, with nontransparent blocks, would stop golems spawning on top but you'd be better off getting the upper floor at the right height, if it's too low you probably aren't getting any golems on the lower floor.
--
Are you getting spawns on both floors?
The upper floor has to block the upper half of the doors and the lower floor has to be 3 blocks under the doors.
Also, so far no increase in iron yield with 43 villagers.
I believe that this paragraph from the link Hexalobular provided explains why:
The average expected spawning rate, if the golems are killed or flushed outside the village boundary quickly enough so that the cap is never reached and new ones are able to spawn in their place immediately, is roughly 10 golems per hour. A higher cap doesn't increase this rate beyond reducing the amount of time that the cap is filled while the newly-spawned golem is killed or removed.
Please be aware that Golem spawning is a RANDOM even occurring APPROXIMATELY every 350 seconds.
Also the yield per Golem is variable. So the hourly rate of iron ingots produced can vary quite a bit.
When I did my long term study of my 16x16 farm I found some hours the yield was as little as 20 bars and a couple hours later one hour yielded over 50 bars.
Just like poker hands, "luck" ie random events are "lumpy" they don't occur nice and regularly like little soldiers marching down a street.
OH! Also on that page is this:
The golem spawning zone is a 16×16×6 area centered around the center point of the village. As long as all the conditions are met (10 villagers, 21 houses, golem cap not reached), then each game tick (1/20 of a second) there is a 1/7000 chance the game will try to spawn a golem. When a golem is to be spawned, up to ten attempts are made to spawn a golem. A random spot is chosen inside the spawning zone, and if that spot is above a solid-topped block with at least 2×2×4 space above it (including liquids—golems can spawn in water, which is key to most iron farm designs—and transparent blocks), then a golem is spawned there.
Which explains why you need the 4 block gap between the two spawning floors and why you need the extra space around the edges of the 16x16 spawning zone to get max. yield.

I've had golems get stuck in the hole back when I was still making iron farms, but that may have been back in 1.7 or so.
