I'd guess that SD for most bowlers would be about 15% of their average. For me, that would be about 29 pins. That would mean,(If i'm getting this right), that about 68% of my games are between 166 and 224 and that 95% are between 137 and 253 and 99.7% are between 108 and 282, which wouldn't really be right(it's been YEARS since i've shot below 118, about 1500 games in between. I'd say that 68% of my games are 175-215, 90% 155-235, 99.7% 135-255, so 10% seems about right, however, that must be too low an SD for lower average bowlers. A 150 bowler would bowl over 195 more than 3 games out of every 1000, so that's somewhat skewed,(mainly by the fact that he would get better), but, using the figures I just gave for myself, which I believe to be very accurate(I don't have exact scores, however), can something be figured?
