Help! Greenhouse environment score is broken
Sagana:
oh, that's odd. If I make sure I start on one of the plants with the "water/many" option (that is, the *first* plant you choose does need to be watered), the sim seems to know which (other) ones do and which don't. In any case, my farmers have never overwatered at that point.

I suspect that the largest sprinkler (360) breaks down a lot less than the smaller ones. I kept thinking that I was having less sprinkler repairs on my nine-plotter than my initial three-plotter back when I was doing gardens, but I haven't done a garden recently and haven't taken good notes on them.
That's the naturally expected statistical outcome, even if all sprinklers are equally reliable. Say a sprinkler has a 10% chance of breaking when it fires. For a single sprinkler, that means after one cycle, there's a 90% chance it works. For two sprinklers, each sprinkler has a 90% chance of working, but the chance that nothing breaks is only 81%. So the more sprinklers you have, the more statistically likely that something will be broken.

Your scenario makes sense, of course. However, these were different gardens with one sprinkler only. One garden had the smallest and was a three-plotter. The other had the largest and was a nine-plotter.

Eh. I blame it on sampling error. Two samples is hardly enough to form a conclusion on.
MyPrecious:
Don't you need at least 3 subjects/samples to test a hypothesis?
It's been a long time :-\…cause and effect?…*goes to make coffee…*
