Here is my opinion, from a parent's perspective. My daughter had a great season in old 4, scoring mostly 37's-38's. She just finished new 4, and her high was just under a 36... but it was because of her FHS vault. It just hasn't clicked for her yet. So even though she was scoring 9's or high 8's on almost everything, those 7's were dragging her AA way down. Her new coaches (we just switched gyms) are deciding if she should go to 5 or 6. She has all of the floor for 6, the FHS vault will click when it clicks, she has a BWO on beam - a BHS with a barely there spot - and the cartwheel (or is it a round off?) tuck dismount. She has the bars in pieces and just needs to put it all together (not a cast handstand yet but 3/4 and she has all summer). So in her case, I can see how competing 4 again wouldn't really be "fair" even though her AA's weren't that high. I know she would rather do 6 over 5, but the decision is ultimately up to the coaches. They have mentioned that if she did 5, she could probably skip 6... so it may very well even out in that case. But I keep hearing that 6 is judged easier than 5, so the whole thing just has me confused. I think she would ultimately be fine with either, but not repeating 4 and I think I would have a hard time accepting her need to repeat it, too.
