So does a diff increase hurt any more or less for a low hash rig vs a high hash rig? At first I thought it would hurt less if I had a bunch of machines. But the more I think about it, it would probably hurt the same?

Increase in difficulty hurts everyone on the network and the same % for all hashing power. The mining calculator for monthly(30 day) BTC earn at H hasing power:

BTC earn = (B*H*N*S) / (D*2^32)
B - Reward per block (say 12.5 BTC) This is where we WIN with kano as we get paid out transaction fees and its getting more important
H - Hashrate per second (1 Th = 1 000 000 000 000)
N - Number of days in month (say 30)
S - Number of seconds in day ( 24*60*60 = 86400)
D - Difficulty

From above you can see, for a 3.11% difficulty increase D will change to (1+3.11%)*D which means on the other side => (BTC earn)/(1+3.11%)
So everyones BTC earn goes down by the same % no matter the hashing power.

Another question was: If the price (USD) rises with the same same % (3.11%) over the difficulty change interval will the payout stay the same.
Yes.
USD earn = (BTC/USD price)*(BTC earn) , now if difficulty go up 3.11% and USD/BTC go up 3.11% :
USD earn = (1.0311)*(BTC/USD price)* (BTC earn)/1.0311 => back to USD earn as 1.0311 cancel.

Just some thoughts -
Even though the general feeling is that we dont want Bitmain to have a monopoly and need more competition this is maybe not always good for us miners. Competition may/should push the cost of equipment down BUT more players will push more Hashing power into the network. One company should have some limit to their production capacity that will limit the flow of hashing power into the network.(i hope, you never know with the chinese)

Also, to raise the Network 13.5 Eh/s (say that is the total BTC network hashing power) by 10% requires 1.35EH/s THAT IS many many S9s (1000 000)

We need to secretly love Bitcoin cash and hope it stays profitable to mine. It pulls alot of the SHA-256 hashing power out of Bitcoin.

Ok, more than I wanted to add.
