The article on the wiki seems to be wrong about the sugar cane growth so i did some experiments by growing 50 sugarcane and then checking on them every 5 minutes. Checking and planting took 20 seconds, so it should be relatively accurate.
The Chance of Growth chart shows the probability that any given sugarcane has grown from 1 high to 2 high at any point. The curve seems to match the curve of the last stage of wheat shown in this spreadsheet
Which supports the idea that sugarcane is grown in the phases, and once it has been through a certain amount of phases, it grows one block. Because wheat does that too, only visibly. I think?
According to the wiki, sugarcane grows after 16 'phases' which last an average of 20 seconds. I know nothing that lasts an average of 20 seconds to do with ticks, but block updates happen roughly ever 47 seconds. This doesn't make much sense, but I also read about a chance in growth rate after 1.8, only on the sugarcane farming page and not on the sugarcane page. So i tweaked the numbers a bit.
After 15 minutes, 36% had grown and after 20 minutes, 72% had grown. 17.5 minutes is an inflection point, so we can be reasonably sure that at 17.5 minutes, 50% are grown. 17.5 minutes is 1050 seconds, or an average of 22.34 block ticks. It is possible that sugarcane goes through 21 block ticks, and on the 22nd, it grows. (Or maybe similar numbers because 50 might have been too low a sample size)
The Percent that Grew Chart shows how many of the remaining sugarcane grew. For example, after 15 minutes, the percent that grew is 47%. This means that 47% of the remaining sugarcane that had not grown at 10 minutes are now grown. There is a strange curve in this chart, but i'm not sure if it's supposed to be there, or maybe i just made a mistake somewhere.

Also, not exactly sure if this should go here
