Wanted to add a comment inspired from an old thread re grand jetes, by someone who wanted to improve. The idea is, whether you are brushing into the jete or doing a developpe with the front leg, to get into your split position while you are still ascending in the jump. Then as you move forward, you have a moment to hold the position before you descend. So the power is in the speed of the two grand battements, front then back, or developpe then grand battement. Then you get that "stopped in the air" illusion at the top.

Thanks for sharing! I'll be sure to try that =)
