@barbarabeeton The "prime time" effect looks much more pronounced than I thought, see
Marcel Krüger's nice analysis. There seems to be factor 4 variation. That means that the reputation scores need to get corrected, US based users score need to get multiplied by 2 and European users need to get divided by 2. After that, @AlanMunn will be higher ranked than @DavidCarlisle. ;-)
