When I watched Paint world streamed live, I do think the peanut rolling has improved a lot. Heads aren't quite level, but certainly not down between their knees. It seems to be getting better, slowly.
I'm also noticing the four beat lope drawing out as well. The horses are starting to really move out more, and actually move in a true three beat lope. No more tender footed looking strides either.
Canting at the rail is still there, but not as common to everyone.
It's getting better, but not all that quickly. Somethings better than nothing though I suppose.
