The Q4 Tourney counts as half Tourney. Unfortunately, the system although shows the Victories with the .5 decimal; it does not show the Tourneys Played with the .5 decimal, as this field was set since we started as an Integer.
Accordingly; you can see now that you played 4 Tourneys:
1st Tourney SE and you won; it shows as 1 Played and 1.0 Victory.
2nd Tourney Q4 and you won; it still shows as 1 Played (1 +.5)and 1.5 Victory.
3rd Tourney SE and you lost; it shows now as 2 Played (1 +.5 +1) and 1.5 Victory.
4th Tourney Q4 and you lost; it shows now as 3 Played (1 +.5 +1 +.5) and 1.5 Victory.
