To follow up on my post Epiphanies...
Today I did another session on "fronts". It was just a short session with 30 treats. The first time Gimme went back to angling her butt to my right, toward 1 o'clock. It was hard for me, but I just waited and waited and waited. She tried several different things to get me to pay up (cocking her head to one side sticks in my mind as particularly cute), she fidgeted a LOT and then... finally she got up and repositioned herself.
It wasn't perfect, but MUCH better, so I rewarded liberally. After that she did a number of fronts that were pretty darn good. Not exactly perfect, but good enough that only a really picky judge would fault them.
So, I'll want to do this same thing for several more sessions (using the platform and the rewarding pattern), then at some point when she is consistently coming in straight and close the first time, then I will try a "front" without the platform. Incidentally, all the fronts were much closer than we've gotten in the past.
As in life, sometimes the best thing you can do -- is to do nothing.
