I don't think I'd have a problem with Levels 1 through and including 3. I have no idea on level 4. (shrug)

In the sub rankings, I, too, hold As up to and including level 3 IF your term in 3A "produce" includes hunting, fishing, etc. as in "make it happen". If you mean produce as in grow, then I have some problems just because I lack sufficient land. Level 4a to some extent. 4B is nailed.
