Indeed, I didn't mean to use the S9 per se, I just meant to use the latest/most efficient/most popular miner, whatever you'd like to use in your estimate. I was certainly not clear.
Re the S19: it's not the hash rate that matters, it's the hash rate per unit energy. The S19 consumes 3X as much power as the S9 and yields 10X the hash rate so it's only 3.33X as efficient. Of course efficiency here is purely transitory as old miners are thrown into the rubbish bin and replaced with these new lotto scratching machines - and the network difficulty adjusts to consume the new efficiency.
