Watching the video of Reme Berringer's winning flight at the Worlds a few years back, it seems the FAI like smooth corners, even if they are a little larger than they do bobbles. But as we all know FIA and AMA are not the same! Personally I like the smooth round corners and no bobbles, but I will give higher points to a sharp corner if there is no bobble.
I don't know about Remi in Spain, but in Muncie, I thought he was hammering it pretty good. The thing that struck me (and everybody else in the crowd) was the extent to which it looked like the airplane lost speed in the corners, and in the maneuvers overall. It was perking along pretty good in level flight, but after the first (what appeared to me to be very hard) corner, it was slow motion from then on. I was very impressed with his ability to keep it from bouncing with all the line whipping and speed variation.
But of course, what generally makes the difference is the cornering. The harder you can hit it without significant bobbles, the better you do. There's no accident that Paul won the thing so many times in a row.
