I have no idea, sorry. I just change my render settings manually as I need to.

I have a preset saved for "production",  "draft",  "mid-level production but not quite draft" etc.  All I do is just load the preset that I want and I'm good to go.  Changing bucket size takes seconds and I can usually tell based on the scene if I need to use a smaller bucket size.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
