If you had a formula to do that, what would that benefit you to have that answer? if the device/hardware has a stated rate of performance i.e 7.7TH, then that is the output you are likely to get from it, when you switch it on, what could affect it differently?

I can only think of things like

- Temperature
- Humidity
- Cooling (positive affect of course)

If the vendor selling the miner states "Up to x.x TH/s" or "Best effort" then it's got other defining factors, but to my understanding, it has a base set of power input it requires to run, and after that, the power factor doesn't make any difference other than the cost to you the individual and up time etc..

Or are we talking about the "Clean Power" vs "Power" because I don't know what the difference is?
