While trying to determine why the WN8 value on my account was different on the Age of Strife stats page (
wot/stats.php ) and sigs to those shown on Wotlabs.net and XVM I stumbled across the expected WN8 JSON data that XVM is now using. This data used to come from the WN Efficiency site at
http://www.wnefficiency.net/wnexpected/ (which haven't been updated since May 2017), but XVM are now generating this data themselves on a daily basis rather than relying on the owner of VBAddict.net to generate them as they were before. I have now migrated the WN8 expected values data over to the XVM version, although I'll only be updating it weekly rather than daily so if a significant change is made it may take a few days for the AoS stats/sig to align.
Personal note: somehow my WN8 rating jumped from 1302 to 1338 with this change, so either I'm playing better or a lot of people using the same tanks I am are playing worse ...
