In my humble opinion a seasoned player would be one who achieved rank and stats by playing ranked rounds which was the ONLY way to improve on your average score, when i started playing the game in 2011, but that all changed with the introduction of the mobile game, i have asked wgt several times how players with little and in some cases zero ranked games achieve an ave score of 64.00! to be told by wgt that players averages are adjusted according to there scores in coin games! yet if I score say a minus 4/5 and on a few occasions -8 in coin games my average does not move by a single decimal point.
So when I speak of seasoned players I mean no disrespect to anyone who plays the game but I do take umbrage at this who manipulate the standing by making no attempt to improve on the ave instead happy to remain at tour pro level yet continue to gain level by level until you get to (as I encountered one night) a level 135 tour pro with all the top equipment and ball to match, needless to say game was over by the 5th hole I couldn't even compete.
So to sum up the seasoned player doesn't need seasoning but a level playing field one were 1 rule applies to all would suffice, but no doubt in your EXPERT opinion i will be wrong
