Well I am no expert but to me that sounds like he is more advanced on floor and rings and not as far along on HB and pommel (?) Nothing wrong with that of course, it is the way it is. My son thinks those skills you mention generally span our level 5 and 6. In US the first level to need 5 circles on mushroom is level 5, and that is our second competition level. And at competitions I have seen many kids unable to complete them without 'falling" at least once. It is nothing unusual. Now that USAG has eliminated the horse part of the routine at those early levels, kids who take longer to get the circles but were good on the horse part (like my sons) are probably scoring pretty low on pommel. But at a meet, in our experience good scores on other events can really make up a couple of lower scores. I mean, psychologically. From a previous thread I think that our gym skews to a higher practice hour count at least amount the US gyms represented here, (even though it is not a super competitive gym) and iirc at level 5 my boys trained about 12-15 hours a week. Level 6 more like 12-18.
