How is it possible that you show ZEC even even with ETH & XMR, much less slightly more profitable.
My RX480's are underclocked and undervolted. Look more closely at the graphs and you will see spikes where ZEC is more profitable.
This has more to do with network difficulty dropping (you're getting more ZEC for the same hash rate and same price).
I understand that everyone's rigs are different, but for me, the profitability isn't even close now with ZEC dropping under $43.
You're looking at the ZEC price and only using that as a benchmark and that's where you're going wrong.
As the price fluctuates, so does the difficulty as miners chop and change.
My profit from ETH is close to 2x ZEC and models indicate XMR could even be better, but I need more mining time with it to prove that out.
All my tests are done at the wall in terms of electricity usage and are extremely accurate.
Aside from the valuing issue, I am curious about something else. I really like that auto-switching feature in theory but if values are quite close and switch often, wouldn't that many switched hurt productivity? Meaning... my experience with both XMR and ZEC is that they take some time to ramp up to full speed. I started mining XMR via Claymore GPU and it started low then continual increases, for several hours actually. Similar thing with ZEC although usually not as long. ETH seem to get to max quickly but I would like that the ramp up time would hurt you with too many switches.
I work around all ramp-up times with code.
Edit: To clarify: worst case ramp up time is ~20 seconds at most but the actual mining when switching is near instantaneous.
