It is exactly my thoughts, I set such a high number of shares thinking of receiving a lot of hash, otherwise I had already thought of reducing it.... I would wait a few days

Also, I not make 3 pools for the competition but for network security, I prefer 3 pools with 200ghs each rather than 1 with 600ghs
If that's the target pool hashrate, and assumming you want to allow 10Mh/s miners to join efficiently, without being wiped out by big miners, then we can calculate a safe N:
N = 200000/10 = 20000
Anyway, i highly appreciate your efforts, man. My posts arent asking you to do anything. Just a gentle and friendly suggestion.
