@LLHBBB i think some of the people who are in the record slots right now also quit cs or just dont bother completing anymore. i brought that up a long time ago when i first completed my collection because i noticed many of the record holders didnt actually have a complete collection any more.
So i think that record should just be updated. Maybe split it in two - current record holders and old recordholders. i mean, they did complete their collection at some point, just maybe not kept up with it.
i also think a year should be a reasonable cut off point. like, if you don't have 2015 complete at the end of 2016 then you loose your record. (keepin an eye on those UR's xD) That way one or two monthly outcomes wont bother the recordholder.
