well, look at it this way, there is no carryover if you're not hitting depth. This is my third centurian. the first two were the NXG material and despite both of them being about 3 years old and stretched out, i can still get 70-80 pounds out them.(that doesn't include the extra pounds from the wraps).
this is my first NXG+ super so not sure what the carryover will be like when its broken in but im expecting to get 720-740 in competition with suit, belt and wraps, which would be as much as 140 pound carryover from with just a belt. most suits i've owned took me two to four workouts to get to proper ipf depth. usually when i first put on a new suit it's hard to get it all the way up into my crotch because of the tighteness, and not having it all the way up makes it even more difficult to hit depth, but the higher you can get it up in your groin area the easier it will be to hit depth.
all you're really doing is stretching out the leg holes a bit. the hips should still stay tight. then, once i know i can hit depth i usually put the suit back in my bag until the meet and use my older suits to keep training.
