My DD is level 6 and goes 13 hours a week... 3 days for 3 hours and 1 day for 4 hours. But a lot also depends on how the time is used... do they spend a lot of time waiting for their turn or are they constantly working? And, of course, the coaching makes a difference too. I would imagine that you made the decision to scale back for good reasons... either it was too much time for your daughter or it was too much time for your family, or both. There's likely to be some sacrifice in terms of scores/skills, but then she'd be making a different kind of sacrifice if she increased her hours (time spent with family, friends, doing homework, etc.). It's all a balancing act and we're all just trying to figure it out as we go along. I say don't second guess your decision, and when summer draws nearer (it's 9 degrees here, so I'm looking forward to summer drawing nearer) you can re-assess the situation. Good luck to you and your DD!
