I would put almost zero credibility in the Wix beta data anymore, which is a shame to say so.
They have been whitewashing their public data to the 2/20=6/20 specs for about a year now, regardless of which filter is listed. Slowly but surely they are converting all their data outwardly. It used to be that the 51515, 51516, and 51348 all had separate different beta data; now they are all the same. How ludicrous is that?
Whatever they have listed for the XP is probably a typo at this point, or it's just their attempt to placate onlookers with a fictitious number. I've seen a lot of typo's corrected over the years from Wix.
In short, it does not bother me in that the XP filters are only rated 50% at 20um; I presume it's just a mistake or some such silliness. What bothers me is that they are either are that careless in their data posting, or they think we're that dumb and not able to understand what it means.
I have emailed them about this topic, but as much as I contact them and don't get a response, I must be on the "ignore" list ...
