When I decompiled one of stats.pyc not sure from who it was:
-1: 'defeatsCount',
0: 'drawsCount',
1: 'winsCount'} battleCounters = {1: 'battlesCountRandom',
2: 'battlesCountTraining',
3: 'battlesCountCompany',
4: 'battlesCountTournament',
5: 'battlesCountClan',
6: 'battlesCountTutorial',
7: 'battlesCountTeam',
8: 'battlesCountHistorical',
9: 'battlesCountEvents',
10: 'battlesCountStrongholdSkirmish',
11: 'battlesCountStronghold',
12: 'battlesCountRatedTeam',
13: 'battlesCountClan'
