DDs gym probably uptrains 10-20%% but focuses on current level for the most part. For instance, my DD, a L6, had all her L6 skills before the end of the summer (bars was the last to come as always for her), but probably spends the last 10-15 minutes of each rotation working on next level stuff like layouts and twisting on floor, fwos and bhs on beam, half on half off vaults...it is the "fun" reward for doing well and hitting all her skills in the "current level" portion of practice. It just wasn't possible for her to uptrain most of the time on bars cause she was still getting her current level bars stuff, but once she had everything, she started working on cast handstands, giant drills w/ a spot, etc. at the end...(but if she has a "bad bars day", which still happens from time to time, she won't get to do the next level stuff...and that can happen on any event for any gymnast at any practice actually)...
I feel a gym that competes a team of girls who can do *all* the skills of the next level, or even two levels above, in a lower level is very focused on winning. That would be like competing my DD as a L5, or gosh, a L4... Even my DD, not the best L6 bar worker, would score VERY well on bars in the lower levels...however, she wouldn't find too much satisfaction in those medals and meets would be pretty boring to her even if she had excellent scores.
