lets use 1 s19 pro and 2 s19

they add to 110 + 95 + 95 = 300 th
watts.     3250 + 3250 + 3250 = 9750 watts +-5%. make it 10 kwatts for sake of easy math

so 300th x 0.0671 =  $20.13 usd a day as per current  viabtc earnings per th

10 x 24 = 240 kwatts a day

10 cent power = 24 usd  loser
 9 cent power =.  21.60usd       loser
 8 cent power =.  19.20.          0. 93 daily profit
 7 cent power =.  16.80           3.33  daily profit
 6 cent power  =. 14.40.          5.73  daily profit
 5 cent power. =.  12.00          8.13  daily profit
 4 cent power  =.   9.60         10.53  daily profit
 3 cent power =.    7.20.        12.93. daily profit
 2 cent power =.    4.80.        15.33 daily  profit
 1 cent power =.    2.40         17.73 daily  profit

these assume flat diff and flat price.
