I was checking my profile, and it appears that within the space of one or two days where I've not been very active at all, the little rankings (xyz Contributions (#abc)) seem to have placed myself, and some other members' profiles I looked at, way up the list. I had been sitting down in the #800-#1000 range from memory. It's as if other members with equal or better stats than me have disappeared or are being omitted from results? As I said, I've not been very active over this time.
I'm not complaining, just wondering what's going on.
