Hello all!
Tell me, please, who know, why calculator on pool (haven.miner.rocks) shows me 3.89 XHV per day, but in fact I got only 1.6

Hashrate at 2.5kH/s was stable and confirmed by pool.
I tried cryptoknight.cc/haven and got the same.....
1. PPLNS - you will recieve your payments within some time after you disconnect from pool
2. check blocks effort/luck in that time
3. network hashrate growth can reduce your payments =)
...
etc... all that with keeping in mind that pools you've checked are not cheaters.
