from Wix specs:
XE, Beta Ratio: 2/20=14/25
Nominal Micron Rating: 14
XP, Beta Ratio: B2=20
OK, but is there a simple way to understand Beta Ratio, Like on the XE Beta Ratio 2/20=14/25 now does that convert to 50% @ 14 microns and 95% @ 25 microns?
Yes, just as I also showed above ... that is how the WIX beta ratio info is read.

Yes, always in microns.
No, 2/20 does not mean B2 (Beta 2). Beta 2 = B2 = 50%.
