Back in April, USBC said its initial research data using its automated Bowlscore ramp showed that strike percentages on string pinsetter bowling under its upgraded specifications were 7.1% less than with traditional &ldquo;free fall&rdquo; machines.
That led USBC to certify the upgraded string pinsetters in a separate category, while saying it would conduct more scoring studies with an eye to making a Sport bowling style average conversion system for string pinsetters.
The headline on my story...

After 3,550 games by 541 bowlers at the ITRC, USBC said there is no statistically significant difference between the scoring pace of the pinsetter types when controlled in the same environment.

Is the sky falling now? After more scoring research, USBC makes string and traditional pinsetter averages interchangeable
