I couldn't do like in the pictures on a bet.
I've never barrel raced and probably never will. However I've always made strides to make everything I do on a horse look as effortless as possible. I know every horse is different but that looks way more counter productive than just a good balanced seat and proper leg use. I think some of that extreme leg stuff may be just for the "show". Just like flashy chaps for bronc and bull riders. JMHO
