Ahhhhhh I see, sorry I misread your original comment. The floor vs round was chosen specifically for balancing reasons - to ensure that Yumako and Jellystems - which have ~50 (a much higher and thus more easily divisible number admittedly) would break even on rare prod modules, and have slight returns on epic/legendary. I choose floor because its more likely to garuntee this behaviour for other crop outputs too - however obviously as you point out, it breaks down a little when the loot numbers are low for sure. I assumed that most "tree" mods would follow high yield number outputs, as its quite a common design and makes sense "many fruits from one tree" etc.
I don't want to change it from floor - as that creates more problems with the balance than it solves. I'd much rather yields be harder to make self-sustaining than the other way around. (Because self sustaining quality items are very powerful, and basically trivialises legendary from a balance perspective)
I would be more inclined to do a precise "add a specific random chance of 1 more item." - the reason I didn't do this initially is people tend to not like the random nature of those output formats. Perhaps it is simply the lesser of two evils in this case.
