I recently started a sugar cane farm, and I'm just curious as to the rate at which sugar cane grows.
I have an automatic piston-harvested farm with 16 cane plants harvested every ~10 seconds. Here are two different estimations of the rate. By "growth" I mean the event of one block being added to the top of a sugar cane plant.
The latter figure is probably closer to correct as it does not involve an estimation of probability.
