Late season average gone up 35 pins

I had open RNY June 3 05 and started bowling in Sept same year. My average started out a modest 153 for first three nights. Now that I have lost a total of 112 pounds and played 20 of 28 nights my 3 night average has gone up 35 pins to 188! High game 257, high series 608. Not too shabby. Two more night to play and hope I can keep it up. Rich
