OK I’m all new to game and tracking maybe it was asked and answered before…So far it gets the data a li’l bit late as we know and thats ok but when I LEAVE a game at the score 0-1 (losing) after losing the first round it does not shown as ABANDONED, it shows the final score like LOST : 0-3 let’s say. And the ridicilous part is when you click on that match you cannot even see your name because it only shows the losing players aftermath.
BONUS 1: This site also does not count the WIN when you leave and the remaining players actually win that match. (But it counts as losing even if you leave the match at some point and theres not your name 
)
BONUS 2: SURPRISINGLY Ubisoft itself manages this and when I clicked the career section I guess it show more reliable data bc I left those matches did not lose at (it made me believe Ubi one for once :D…
