Your average will only move from ranked strokeplay rounds, not from Blitz games. Furtheron, you might want to return to those good scores of 37 / 38 / 39 instead of shooting 54++ over nine holes - your saturated TP average will never move up again.
For better results, you might decide to get some decent wedges (Ping or up) and perhaps not waste so much credits in high-stake Callies - those lvl33 will do, or Srixons, or WGT Tour-SD.
