Here is Gambit practicing her sit stays at Tads house this weekend, I was giving him a demo on a few of her rally routines. She hovered a few times when I first started training her. I worked on leading her head backwards with a treat till she sat all the way down. Now she does it naturally, but yes they do go for comfort first. I failed to qualify last yr one time with Xander, because I thought he was in a perfect sit stay, walked all the way around him fine, then we moved forward only to have the judge tell me that there was a half inch between his butt and the concrete floor on his sit on each of the 3 sit stations grrr. Looking down on him at my side it looked like he was sitting, but he was obviously not going to put his buttt down all the way on the cold floor, first and last time he's done that as I bend over and check now.
