Thanks for sharing LA-Koperboy! Very interesting results.
Your 20 yo is one of the better documented PA elastic effects I've seen. The link to HA and DR seems very plausible too, given those are secondaries in PA training. I personally haven't used the 1v1 weeks to start a trainee's career, but it's not a bad idea. I typically just rotate training every week, and try to get PA up quickly. Makes the trainee a little less painful to play at PG in Cup games if they can get a bit more PA.
Great results on those players though. Can't argue with that!!
Thanks again.
