My DD is a L4 and goes 6 hours a week (2 hours, 3 times a week), which is on the low end for our area. She is progressing pretty well and it's a good fit for us. If she chooses to continue, the hours will obviously increase. I am hoping that "only" 6 hrs a week as an L4 will maybe help her stay in the sport longer and maybe prevent burn-out (b.c. 6 hours of any sport is actually a lot in comparison, though I fully know that with gymnastics it's different)...no reason to race towards more hours at this stage in the game. As a PP said, it's all about the best fit for your DD/DS and your family.
