I entered a few plays in the stats, and unefortunately I realised that I had a single very important rule wrong : once the doom track is full, you are not eliminated, but the ancient one awakes ! So i've logged most of my defeats as defeat by elimination, when only one or two from them are real eliminations.
Hopefully, it won't have too much effect on the total stats.
I guess i've played the 1987 "Arkham horror" (no final battle after the doom track is filled) one time too many.
Sorry for the little disturbance !
