LOL, try to search in the forum. this is something known for 2 years
there are brackette : 18-21 yo, 22-25 yo; 26-29 yo; 30-33 yo
it's quite normal that your fast trainer slow his trainning when he is 22. and a 25yo player can better than your 22 yo easily if when he was 21 yo he has better than the one now 22 yo when he(22yo) was 21 yo
42Q and 7m6 mean they are just good trainner but not the best one,
