Once a week is more than enough.
And regarding the ranking: I'm flattered, of course, that I'm listed near Palladin :D :D :D (even though I'm not actually close to him...:D), but I like the ranking itself, and it's not just because of that. Overall, I think it's worth continuing to develop this ranking.
За то что нейтралы не бегают за единичкой, для меня это уже стоит того
