I've started keeping up stats with rewards with the CKPool Monitor created by Zach.  The stats don't lie.  You see the stats in AMOUNT PER TH/s in each column.  I have not been at kano long enough for the 30 day and 60 day column to catch up with the 7 day and 14 day columns yet.  Which means the 30 day and 60 day columns have insufficient data at the moment.  Give it more time...

You'll notice the 14 day column average per TH/s is 0.00832183 BTC and the 7 day average is 0.00813792 BTC.  I gave the 14 day first because it's more sufficient data over a longer period.  Also, I have not had all of my hash added to the pool.  I actually took my hash away a couple of times and brought it back.  Both times was for about 24 hours.  YET, I still got paid while I was away when blocks were found.  I came back the moment a block was found.  I've determined it's best just to keep all your hash there during slow times and good times.

On NiceHash at the moment, one gets paid in PPS at a rate of .0047 per TH/s.  Now compare that to .00832183 over 2 weeks and .00813792 over the past week at kano.is

I have 104.5 TH/s pointed to CK/Kano Pool.  It was 94.5 TH/s but I pointed another 2 x S7's at the pool yesterday.  Also, I needed to add the data of the most recent block found at kano.is to the chart below.  I felt this was sufficient enough for now for you to get an idea.

The reason my payout for the last block was less than previous even though I had more hash is because the pool had increased in hash rate.  Also, the difficulty increased as well.
