The thing is that frontloading and backloading are not choreo concepts.
But evenly distributed jumps is not a choreo concept either. Most pieces of music don't have a climax exactly every 30 seconds or so...sometimes I see evenly placed jumps having no connection to the music whatsoever, jumping whether the music is soft or strong. And people do evenly distributed jumps for TES reasons as well--it's too risky to backload all the jumps but they still want to get the bonus benefit on some jumps. No one with evenly distributed jumps ever puts their most difficult jumping pass at the very end. They always do it either 1) at the beginning, or 2) right after the halfway mark. They are also doing it for TES reasons.
