Train mode in Parallel seems broken

I am a tester for carv. I have hit level 30 on Parallel turns for all 4 skills. My ski IQ in parallel is 132 this year (135 last year). The app no longer gives me any advice that helps me improve that SkiIQ. It sends me to “Making my snowplow smaller” but I already am doing that at level 30. Last year I improved because Carv was telling me I needed to work on edge similarity, early edging and other things that were more concrete and doable. I generally like the new train mode for the other turn types but it seems to fail for parallel. Also, what actually makes a turn “Parallel” vs “short” or “carving”? Obviously short turns are tight and carving generally is a longer turn but when does “Parallel” kick in? medium turns? Thank you for the help.
