Thanks for setting this up, I’m finding it useful as I’m at the point of changing from max seed to sustain with a few of my crops!
I have spotted a couple of places where I have a little better percentages though, it may have already been pointed out to you, but thought I would give my input to help improve this excellent guide:
Ancient Oat, max seed
Swap the gleam in your example to mud to keep same max seed but bump crop up 30%
Oortian rice, max seed
You do point out that you can improve crop with seed but it varies, however all of my rice is at 120/115.
This is tricky to see where the differences are, as my rice fields have a different structure to yours, you would be welcome to come look, if it’s of interest.
