So, what happened to the total hashrate here? Where'd everybody go? Don't tell me they buggered off to mine Bitcoin Cash?

Bear with me I'm new.
I studied up on pools a couple months ago and decided on Kano after considerable research. I'm just now coming back to check my numbers again and get some info to get started. In the next 3 weeks I've got 5 S9's coming.
Total BTC avg hashrate over the last 7 days: 10003 PH/s (from fork.lol)
Kano avg hashrate over the last 7(6 really) days: 50.59 PH/s
My expected hashrate 67.5 TH/s
Kano's share of total avg hashrate over the last 7 days: .00505748
My expected share of Kano's share of hashrate: .00133426
Or, my expected share of total BTC hashrate: .00000675
From fork.lol:
$100629.93 avg block reward/block - 7 day avg
$13674.19 avg fees/block - 7 day avg
yields: $113674.19 avg total reward/block - 7 day avg
5.79 blocks/hr - 7 day avg
yields: 972.72 blocks for the last 7 days
972.72 blocks x $113674.19 = $110573158 total rewards for the last 7 days
So, my expected share for the last 7 days: $110573158 x .00000675 = $746.14 or $106.59/day

Now for Kano's numbers for the last 7 days:
103.05 BTC total reward for the last 7 days
minus the pool fee 102.12255 BTC
or 14.59 BTC per day
14.59/50590 THs = .00028838 BTC /day /TH
My expected Kano share: .00028838 BTC x 67.5TH = .01946537 BTC or $138.20/day (at today's rate of $7100)
or $967.43 over the last 7 days.
That's pretty damn good compared to my expected share above at $746.

There's probably an easier way to calculate this to compare pool performance against expected overall share rate but I'm new and this was my easiest route given the numbers available at fork.lol.

My numbers look right to you?
