Im still plodding along with my bot for DMC - Im making the bots swim atm.
Anyway I remember a while ago I read a post of someones (maybe PMB but I dont know) saying that they didnt know what the "upmove" float is for - well it can be used while swimming.
So upmove will move a bot up if positive and down if negative, while in water, irrespective of bot angles (just like players can do).
Just thought I would share
