you're quite right Todd but in the class i do they do have people going on to show dogs and we learned how to give the signal
to stand and/or say it as well and MAX doesn't sit unless he gets the hand signal and stands till he does. I LOVE OB classes we did!
we also learned sometimes your dog is doing things correctly and WE can be the reason for errror, confusion, or a halfway command being done.
So I learned alot about my mental attitude, posture and doing my homework too when training Max, beau and peanut.
it's funny when anyone says SIT MAX or SIT PEANUT and they won't
they ask why.........I tell them " you didn't use the hand signal"

( i love it drives my 22yr old daughter NUTS!--paybacks are fun)
OH we did same training like you stated TODD and it's great here it's called the Vollhard Positive Reinforcement method
and with Max we worked towards NO treats , only praise and quick pat or hug from me
BUT if i am attempting something new or dangerous (like lettign them out off leash alone due to my surgery) then i use treats
all for 2 rasberries too haaaaaaaaaa
