Most the big drop-offs I saw in my team happened around old L6, while struggling to master some events for L6, having to stay in L6 multiple years, etc, usually combined with being around middle school age which causes growth spurts, fear issues, and starting to feel 'old' for that level.
Although I aged out before I got to this point, I don't think I ever would have competed beyond L7 or a somewhat substandard L8 due to a lack of good coaching on floor as well as coming to realize that my strength to weight ratio was plateauing and would limit me (especially on bars) due to my body type.
