PvP balance
From YPPedia
PvP balance is the current result for overall PvP battling.
Each win is worth +1, each loss is -1; The "Recent PVP battles" list in the crew "Overall battle stats" page, showing the PvP battles for the last 60 days only, so weekly or monthly equation is recommended.
- All disengaged battles do not count, no matter who disengaged.
- All battles proven as arranged - do not count
- All battles between same crew - do not count either
- Example: 10 PvP battles with 3 wins, 1 loss and 6 disengaged battles gives a PvP balance of +2.
An alternative method of calculating this particular statistic is to subtract the PvP losses from wins.
NOTE: This scheme of calculating balance appears to be quite specific to the pirate Gulfstream, his alt's crews and one flag. See Gulfstream's rules.
