No, B2=20 is 50% at 20 microns. B20=20 would be 95% at 20 microns.

Beta Ratio: B2=20

50% efficient @ 20 microns

In that case it appears the regular WIx filters better than their synthetic.
it says 2/20 6/20

Yep, the debate on why the XP is only 50% @ 20 microns has been going on for awhile now.

They would probably claim its to keep the filter from plugging in high mileage oil change intervals...

So with what we know, is the NP/XP really worth the increase in cost over the NG for the performance delivered?

Filtering with the NP is not as good according to the published numbers and according to the specs for the NAPA filters (F150 5.0L) Part Number: FIL 7502(NG) vs PFL 47502(NP) the flow rates are the same at 10 - 12 gpm

I don't get it.
