My daughter was not typical at the time in her gym, but she started as Xcel only, then went from XD to Level 9 (with appropriate score outs) when she was 14. Since then a few others have followed her example and come over a little earlier as Level 7s. It's worked out well for her-- She did a year as Level 9, went back to XD, and then another year back at Level 9. She's staying as a 9 or 10 this year for her senior year. The big caveat is this wouldn't have worked if her gym wasn't supportive. I don't think other gyms in our area would have accommodated her moving back and forth.
