Yes and how are each section participating equal weight towards the aesthetic when the sections are so disproportionate? They don't participate equal weight to the performance that's the problem. If backloaded programs were accurately penalized for the lack of proportions and for the unability to express the music and the theme, there wouldn't be need to actually require a number of jumps in the 1st half, but it is not happening so then that's just what you need to do.
I don't think requiring that for example 2 jumping passes must be in the 1st half kills all creativity and makes the programs all the same. It actually still leaves a lot of liberty to put more in the 1st half or on the contrary to still backload 6 jumping passes which is still a lot. And if for some reason you want a concept with all your spins and footwork before the halfway point, i'm sure you can still do it and have the two jumps back to back just before the 2mins.
I just find it insincere to defend the backloading of all the jumps in the name of artistic freedom when none of the skaters doing it are doing it for artistic reasons and when the defense of those skaters have been "but they are just using the system, they are playing the game".
Again, people skating programs with evenly spaced out jumps are also doing it for TES reasons, so it's not possible to claim that all evenly spaced programs are done for artistic reasons. I'm just saying that programs can be artistic or not artistic no matter where the jumps are placed.
Just because a section doesn't have jumps doesn't mean it's not contributing equal weight to the overall aesthetic. That's like saying a novel must have an action scene in each chapter in order for each chapter to contribute equally to the overall story. In fact, the overall story would be weakened if each chapter had to look the same. If proportion = jumps as you think, then the ISU would have just come out and said "contributing equal jumps to the overall program," not "contributing equal weight to the overall aesthetic."
As viewers, we've seen decades of programs where the skater starts out with a few arm motions, then proceeds to stroke around the rink toward their most difficult jumping pass. A totally backloaded program starting out with footwork and choreo was totally unique and refreshing to me, and made me think about the different artistic possibilities of a program. You want to require jumps in the front to force the one or two skaters in the world capable of doing a totally backloaded program to do a conventional program layout that 99% of skaters do and have done historically? That really decreases the diversity of programs IMO. If you don't like to see 2 minutes of footwork, you can always skip that skater and watch the 99% of slayers with evenly spaced jumps. But why should everyone have to watch all the skaters using the same conventional layout just because that is your preference?
