The count right now is:
s7@~5.13TH/s
s7@~4.82TH/s
s7@~4.97TH/s
s7@~4.95TH/s
s4@~2.29TH/s
sp20@~1.51TH/s

for a grand total of ~23.67TH/s

The ROI is theoretical because I just started mining again and when I loaded up my old wallet there were still bitcoin in there from the cpu and gpu days which I used to get all the hardware. I have positive balance in my wallet so I'm considering it profit.

I have 5 scrypt miners with a total of 6.57MH/s those are mostly just as desk ornaments at work and to mess around with altcoin
