Melonhead66630: To the best of my knowledge bracket scores don't show until both opponents have played.
Otherwise your opponent would get to see your score and know what he/she had to shoot.
That's logical, corresponding to RGs, but not quite correct.
I just joined a Bracket which filled while I played. Now both my opponent's and my scores are shown in the Bracket but not in our score histories. I even left the "Open Brackets" list open to have a look at it later - it was marked as "need to play" but it disappeared by itself (Javascript), without me reloading the page.
The link in a mail notice fails, too, pointing to the Tournament description page with no link to display the Bracket.
But, it is displayed in the Bracket results section with the mark "only tourneys that I entered" checked:
The score did already modify my average though, so I wonder when it will be displayed in my own score history? My guess is, when the first round is over(?)
Edit: Picture added
Edit 2: Returning to the Closed Brackets tab, that Bracket is gone, now it shows
"There are currently no tournament results to display matching your filter settings."
Now I can no longer access that Bracket :(
Nevertheless, it's still active, I found it through the Bracket tab of the game window. Your chance, TRutger!
