Yeah while making the mod I have an absolutely massive (over 3000 boxes) spreadsheet for all my stuff. The trees don't work exactly like berry bushes because of the harvest-per-year. Once they fully mature, they reset much higher than 30% - to represent the 'fully mature' aspect of the tree and that it can spawn harvests multiple times per year after the initial few-year growing period.

Is it the harvestaftergrowth stat that defines what growth they're at when they're harvested? If so I've fixed my spreadsheet. Based on that, breadfruit is a real outlier among fruit, it's almost 40% more food than any other fruit. Granted I was growing only exotic plants when I got my colony established, but it does seem interesting.

The other thing I noticed while playing is there didn't feel like a huge incentive to diversify my fields unless I was making the super meals. Would you consider fine style meals that require 2 of the 3 growables at more nutrition per meal than a normal fine, and lavish at 3 of 3 with again, more nutrition? I'm just not sure if there's much point for me to have grain, fruit and vegetables growing unless I'm cooking those super meals, which I can't early because my cooks are all down with food poisoning.
