We are not in one of those gyms but I would guess that those parents are saying to themselves "why do gyms allow their girls to compete at levels they clearly are not ready to compete? If you can't consistently stick a routine, you have no business competing it." I think it really is just a different set of beliefs in what does "ready for competition" mean.
yes - first world problems...
DD was recently at a meet where she was called up and awarded medals in events that she didn't compete! - because they went out all places... crazy
perhaps if you are talking compulsory where a program may drill the routines forever to perfection (Why?! I have no idea) and do no uptraining. But very few gyms obtaining 37+ consistently in optionals are in this predicament. Those girls getting 37+ typically have the skill set for the next level. Perhaps not enough to get a 37 but certainly to get 35+. At some point, those gymnasts were "held back" from competing so that they would go into the next level capable of earning 37+ - whether it was in pre-team where they trained entry level skills/routines or they repeated a lower level to give them the edge - train up, compete down.
It is what it is. just a difference in coaching philosophy. I think it is so noticeable because most gyms don't have this belief, so when parents and gymnasts come across it at meets, they don't understand it.
Having my dd go up the ranks, I have come to realize that it often washes out after several years of level 10, if the gymnast can get that far and has developed good form along the way. However, most gyms recognize that not everyone is going to level 10 and they want their girls (and boys) to enjoy their time in the gym, feel success by learning new skills and routines, even if they are not medal worthy. The motivation and fulfillment doesn't come from the podium at the meets but from skill development in the gym.
