The "book" is out if anyone is curious like me. Level 5 seems to have literally zero routine changes, so that's good. Level 4 floor took out the stretch jump, which caused my son more than zero problems over the past two years, haha. Glad to see that gone! The scoring changes are interesting, and will take some adjusting too, simply because we'll need to rethink what a "good" score is! The level 6 routines are very different, but I don't know enough about anything beyond level 4/some level 5 to even know what some of that stuff is! We also don't do level 6 at our gym, so its a moot point around here.
My son is enjoying the "off season" right now and pushing for those bonuses! He's got a minimum of two years at level 5 regardless (because he'll be competition age 10 this year and no level 6 at our gym), but he wants to go D1 this year instead of D2. They won't make that official decision for a little while and he's a determined little bugger.
