I did the math myself recently, (much as I love Kano, I can't pay my bills with said love, and although it's been a fantastic streak, I was looking at the numbers from before to forecast what may be on the horizon...shame I didn't start 6 months ago though, the luckiest day ever in history of the pool was my birthday  ) and came to the following numbers.

I use BTC.com pool as a benchmark because they simply buy your hashrate without any concern for blocks as a PPS pool. Mind you at the time I did the numbers there were paying .00007btc per 1TH/24hrs and they were very competitive but presently it is 0.00006369.

0.00006369 * 13.5 = 0.000859815, this would be your daily payout from that pool, per one 13.5 S9.

I will use my personal example from last week since I have the exact numbers.
I left one 13/TH Antminer on Kano as I experimented with Slush, I used five 13.5/TH to experiment.

For 5 13.5, 67.5TH/s, I had following results:

Obviously the reward changes a bit as the total hashrate of the pool is different every time but as you can see, if we use .000265 as the average reward, divide by 5 and 0.000053 per block, per 13.5TH S9.

Now between BTC.com's 0.000859815 and Slushpool's 0.000053 per block, Slushpool would have to hit 16.22292452830189 blocks in order to equal BTC.com in pay.

https://blockchain.info/pools?timespan=24hours  As you can see Slush is not so hot these days, they barely find 16 blocks a day. Between Slush and BTC.com pool; it's a gamble with Slush, if they hit above that mark, you're up for the day. This sounds better for Slush now, when BTC.com was paying .00007, it was really tough to justify Slush.

Here is where it gets complicated in comparison to Kano, due to the extremely long ramp-up 'N' time as well as the fact that this pool has grown exponentially in the past 2 months.
Look at these rewards from the crazy lucky streak, back when I had only three 13.5 plugged in, and fully ramped up.

Here we see that my hashrate did not change but the pool grew from 87.93 to 96.95, just over 10% growth. In order to try and make it a relevant comparison, let's compare blocks 515733 and 515930 as they have the closest reward value. (albeit off by .025 btc)
My value: .00544(round up 0.0001 value due to 12.527 vs 12.552) / 0.00570= .95263158
Pool Hash: 94.49 / 90.37 = .9563975
Therefore we see that the change in pool hashrate reflects on my reward in almost 1:1 proportionate impact, likely even closer in value than we see here due to decimal place roundoffs.

For my own intents and purposes, it comes down to the math between BTC.com's  80.5 (my hashrate) * 0.00006369 = 0.005127045 daily payouts, or taking a chance on Kano.
I never actually got all 80.5 ramped up yet on Kano but my closest were the following:

This was during the time I experimented elsewhere while leaving one 13.0 on Kano, and then coming back.

Unfortunately I need a better understanding of or a better written explanation of the ramp process with regards to changes in personal hashrate and its effects on ramp calculation in order to ascertain whether there is some kind of sweet spot.. for example whether going to Slush or Btc.com until Kano hits x% shares, and then coming back would be beneficial or not in comparison to just sitting on here the whole time, etc. (I see the

Would love to know more details on how exactly that long ramp up impacts rewards (I am not a math wizard by any means but I am genuinely curious) and how the calculations fluctuate when you're not just plugged in 24/7, because even after having experimented around, I'm not sure if I'm calculating the differences correctly or able to calculate hypothetically since I'm trying to make sense of the results to figure out the formula (ramp up vs ramp loss), nor am I sure whether I lost money by jumping to the hot pool then coming back or not. (I understand the fundamental difference between PPS and PPLNS, but the long ramp up period throws me off on calculating possibilities.. sometimes shifts get paid 6+ times, sometimes only 3-4 times.. etc)

As you can see though if you do stay fully ramped up, if and when this pool hits a lucky stride, it blows any other pool out of the water. Look at the last four blocks of March, 0.02208 BTC with 41.04 TH's in 3 days. I don't know what BTC.com was paying at that time but even with a .00007 assumption, 3 days would've only paid 0.008505 on three 13.5's. 0.02208 - 0.008505 = 0.013575 BTC. Huge difference for 3 Antminers. Of course one has to consider the ramp up time leading upto this streak, and the cost of that along the way.
