i am mining in aropool.com and have noticed some strange behavior.
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 :
