Yep…IGC was pretty comparable to USAG back in the days, not anymore. Every girl’s journey will be different, but in general on the system level, IGC is way less competitive; and the skill progression is way different than DP, which make the transition into DP harder, and harder than from xcel to DP.
Fresh example, both IGc and xcel gold/platinum had states this weekend. Only 6% of the xcel gold girls can get into regionals (placement based), versus the majority of the IgC girls can get into regionals (score based and the score is very achievable). The difference in the standard of “excellence” further translates down to how they train, how they progress and how they select.
With that, Gotham and a handful other other gyms dominate IGC. So if this is something you are interested in pursuing, Gotham is the place to be. But if this is not your end goal, aim for Gotham DP, or go to a program that has a solid xcel program with the possibility of transitioning into DP when ready.
