RE: Trim memory with Futaba T6XA
No, that's not too much. It does suggest however that you are a clevis turn away from being dead-center on your trims. Why not make the mechanical adjustment and be perfect?
Test fly the model....land....make the adjustment...voila!
Do this for all your planes, and you won't have to worry about what trim goes where each time you fly. Trim Memory, etc is just a fluff feature. It's still best to do it mechanically.
