Help! Greenhouse environment score is broken

I'd guess you need a high enough percentage of samples to be statistically viable.

I wouldn't really consider 2 sprinklers a statistically viable sample, and there doesn't appear to have been an effort to conduct a scientific study on this in any event. Conclusive would be if somebody carried out a detailed study of the actual sprinkler failure rates, or dissected the code to determine this definitively. This, however, is not presently believed to be worth the effort, and sprinklers have not been found to differ substantively enough even on an anecdotal level to warrant the effort.

It's not, that why I said "I suspect" instead of being more sure about it. It would make sense that the more expensive one would break down less, and that happened the one time I actually paid attention, but one comparitive sample does not make proof. If I cared more about crop-growing, I'd really test it, but, alas, I don't. I will be doing some in my Alpha/Apoc hybrid soon, but no sprinklers as I'm categorizing that as Medical (running water).
J. M. Pescado:
There's no "more expensive" sprinkler. All sprinklers are actually the same price per unit area. The 360-degree sprinkler obviously has 4x the area covered and therefore costs 4x as much, but adjusted for coverage, the sprinklers are the same price. If you use 4 90-degree ones to cover the same 4x4 plot, you will pay the same amount. Of course, a sprinkler will be broken more often, but there is a lower probability that all sprinklers will be out of commission at once.

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…*
And also: You can never prove a theory, you can only not disprove it. Theories are, therefore, assumed true until proven otherwise.
... I've heard.
