I have about 44 kh/s and usualy I check every 12 hours to see my inputs, sometimes their is a huge jump in coins received (e.g I expect to find 200 and i see 500).
Is this due to the pool staying back in payments, pool luck or is there a super- block feature (cant see that in ANN)?
When you win a block you get ~390 ARO, that might explain the gap.
You can check who won the 100 last blocks here to check next time : http://aropool.com/blocks
This is definately it!
This 390 ARO bonus is a pool feature?
Is it deducted from the total 980 that all miners split?
Yes, the pool reward systems works such that 40% goes to the miner who solves the block, 30% goes to historic shares and 30% goes to current shares
Thanks for the explanation. I didn't understand why I too had these ~390 ARO.
