It's at the limits set coz we need more miners in those ranges.
The problems before, when the pool has taken a dive, have been due to having too few large miners.
If one person leaving, puts us in the position we were in, at the end of last year, then I need to resolve that.

... and in case anyone has delusions about the 10BTC ... I've been risking an exceptionally large % of all my BTC, over the last couple of months to get the pool size back up, and it's been working, and that 10BTC more is not a small % either ... it is directed where I currently deem mandatory.
