[Frameworks] 16mm Double perf clear leader

[Buck Bito - Movette]

Hey Scott,
I just couldn't let 3% sit there as a description of the difference,
because we are often measuring shrinkage on archival materials and know
that anything over 1.5% is dicey running on sprocketed equipment. I think
the proper math is:
long perf - short perf / ((long perf + short perf)/2) * 100
long perf: 0.3"
short perf: 0.2994"

0.3 - 0.2994 / (0.3 + 0.2994)/2 * 100
= 0.2%

So I think the correct difference is 0.2%.

-Sincerely,
---Buck Bito
