My thoughts are if trim is low single digit don't accept - AT is working and adjusted for the different conditions today than when first set up and your base tune is correct. But if the trims are 15-20% consistently than you need to accept as your base tune is off.
 

sounds like you're on top of it already. @Ygransom gave good advise above.
only thing i could add is that the wideband O2 (which is AT with ability to drive an AFR gauge) along with an AFR gauge would be beneficial - you can see in real time what the AFR is doing.
then wrt accepting trims or not, if it's reading a bit lean at certain throttle % and revs, accept trims at those points if they're trying to add fuel, and vice versa. much faster than plugging in laptop after every spin to try decode what's been going on
 

I don't see why you would want the AT after a proper dyno tune?
Mine has been disconnected, although left in place, in case I give NOS a try.

one day the PC5 firmware went corrupt and made the bike run lean. the heat browned the exhaust header dome nuts and baked the cam cover gasket. if it wasnt for my trusty AFR gauge i probably wouldnt have noticed until the engine seized.
i'd imagine it's also handy for people who may want to play about with exhausts and stuff

I installed AT before I had the Dyno tune. Mine is now turned off in the software

Same here.
Nels (my tuner) convinced me to leave it mounted in case I wanted a NOS kit.
