I really think the changes will be beneficial for those already on the elite track and have been injured, or struggle on one or two skills and hopefully more girls will continue ipfor longer. I'm not sure it will help late starters, it depends on the gym. When my DD was trialling for squads she was 6 and considered too old by one gym and wouldn't get strong enough quick enough. Only one gym of the 5 within a hour drive of my house would look at girls of age 7 and possibly develop them, there are just not enough resources/coaches in the other gyms and they are putting their time into girls they have nurtured themselves from age 5. It's tricky for late starters but not impossible you find the right coach. My DD caught up training 15 hours a week over the summer hols.
