That is what coach Sommer said in a podcast I believe . However I believe there are no studies on this for the simple reason that it is hard to quantify and qualify genetic potential in a scientific study . Furthermore , you need a good number of participants throughout a 12 year time . A little comment on the 34 year period I believe that varies . If we look at the genetics we have a hypothetically 100 % boundary at some stage . However , genetics not only define where your 100 % lies , but also how fast or slow you get there good or bad kinetic learner ? and how steepflat the whole learning curve is . We also have to account for when life gets in the way of reaching 100 % potential . Gymnasts are able to train 30 hours a week , ordinary people are not . That has a huge effect on when and how fast you climb the curve . Also , ordinary people do not have expert resources to guide them up the curve , that also plays a role . Some food for thought .
