@Toxcatl , Der- Ryan has used a scientific approach to support his thesis by
1-providing hypothesis
2- doing tests and experiments
3- comparing results
4- support his thesis with proof.
I am not judging to which extent his thesis can be correct 40- 60 - 80 % .... so instead of being rude by saying his thesis is ridiculous, follow a scientific way in your reply and show him and other viewers some examples that prove the opposite .... ( for example show results of 4-6 players with 104-105 difference according to his hypothesis that are not fast trainer)
P.S. one important thing that should be taken into consideration when doing tests on players, to be scientifically approved. The tests should be in high levels at level 50-59 with 129 million value. so the results of testing players in low or mid levels who have values below 128 million are irrelevant and void.
Der- Ryan. Thanks for sharing your thesis with us. Keep on
