Writing down your scores frame by frame is a great idea for figuring out where your problems started and where you need to make changes and what parts of your game you need to focus on fixing.
Single pin leaves = 10
single pin spares = 5
single pin spare % = 50% = 55 from your score at 11 per miss
multi pin leaves = 15
multi pin spares = 8
multi pin spare % = 53% = 77 from your score at 11 per miss
total missed from score = 132 or 33 from your average because of missed spares if you made your spares your average for the night would be 169 + 33 = a 202 average for the night. Subtract from your total the number of spares that were splits, nobody expects to make splits, and you didn't mention, so I figured they were all makable spares.
Strikes for the night = 16
number of total possible strikes per game = 12 x 4 games =48
strike percentage for the night = 16/48x100 = 33%
Everyone makes bad shots, you seem to have run into problems in the second game in frames 2-5 where you left a string of multi pin spares, what happened, was the ball going high or light what leaves were they?
I also saw a couple of 3 counts I take it you missed to the outside and the ball picked off the corner pins here?
Was the ball flaring back over the thumb or starting over the thumb and flaring away from the thumb? If it is starting out over the thumb (most likely) your fingers and thumb are in line with each other, try keeping your index finger in line with your thumb and getting your thumb out quicker should get the
Track off the thumb. You can still throw the ball with forward roll without pulling the
Track up over the thumb, try your regular release but following through with your thumb at the two o'clock position instead of letting your thumb go all the way around to 12 o'clock.
You are very close to taking your average up at least 20 pins have you looked into getting a coach?
