Your level has nothing to do with any challenges that you are facing. Your tier, Master, sets the difficulty factor. This game, like real golf requires lots of practice. In the year that you have been playing you have completed 63 ranked rounds.
Putting is a challenge for almost all of the players here. That you have attempted fewer than 2500 could be a factor in lack of success. If you check the stats of some of the best players you will notice that they have all played a lot of ranked rounds and struck many, many putts..
I started this game in September of 2012. I don't consider myself a very good player or putter. I have played 6651 ranked rounds and 115,279 putts.
Fmagnets, one of the best players here, also started in September of 2012. In that time he has played 26,766 ranked rounds and attempted 393,022 putts. Those are some of the reasons he is a much better player than I am.
You need to play and play a lot to get better.
