I have to agree with a previous post that stated that determining one's true average
is very difficult. I started bowling in the early 60s. My first sanctioned average was
138. By the time I graduated high school, it was 167. By age 21, it had risen to 186.
I was born and raised in Pittsburgh, which had its fair share of very talented bowlers, including Buddy De Luca who holds the distinction of winning the Petersen Classic twice and Rich Collier who is in the Pennsylvania bowling hall of fame. At least in Pittsburgh,
the lanes conditions were darned tough. For years, you could count the number of
sanctioned 200 averages on one hand--and still have a finger or two left over. There were
no walls, crowns or blocks in those days. None. Even the introduction of balls like the
famed Columbia Yellow Dot and the Brunswick LT-48 did not raise averages by any appreciable amount. The real catalyst that started the average explosion here occurred in 1977, when the ABC dramatically relaxed the lane dressing rules overnight. Once they started to allow crowning, the average explosion took off--- overnight. Since then, the introduction of stronger balls accelerated averages even further. However, it was the relaxation of those lanes dressing rules that really did it.
