Solo Shuffle games/win% incorrect

at it says i have played 181 solo shuffle ‘games’ as affliction, won 176, and my win rate is 97%.

in game, it says i have played 1066 rounds and won 556, which is about 52% win rate.

this seems like a big mismatch, unless i misunderstood how the ‘win%’ calculation on the armory page works. maybe it’s counting at least 1 round won in a match as a ‘game win’? if that’s the case, i’d say that’s a very confusing take on win% and not made clear on the website.
