For example with cabbage seeds. If I don't water them, the seed yield is 80%, if I do water them it is +40% or 120%. So for 2 plots, 1 watered and another not, that is 80% + 120% = 200% or 2 seeds, so ultimately 1 to 1. So statistically if I plant 4 fields of cabbages and only water the plants in 2 of the 4 fields, in the grand scheme it averages to 100% yield. So I would expect that while some days it is a little more and others a little less, I should roughly get an even return of seeds for all 4 plots (ie, 4X9 or 36 seeds back).

I mainly want to make sure that there isn't some sort of bizarre math happening where % above 100 has a unique multiplication factor to it.... like I assume 120% means I will for sure get 1 seed returned and there is a 20% chance (1/5) to get a 2nd seed. Sometimes algorithms can have some unintuitive consequences and I just wanted to double check/verify.

Thanks!
