Ok, I'll try to clarify:
On this page:
https://miningpoolhub.com/?page=home&normalize=nvidiaYou can see the profitabily of each algo for NVIDIA cards. I assume that this is calculated by using the BTC/GH/Day ratio (you can find it here:
https://miningpoolhub.com/?page=home&normalize=none ) and by adjusting this with a "profitability factor" for each algo. This profitability factor reflect the efficiency of nvidia cards for each algo. If you select AMD, the factor are obviously not the same.
So, my first question was: Is it possible to have the details of these ratios.
That information isn't published anywhere that I'm aware of. Why don't you email them and ask?
Second questions:
With the yiimp base pool, you can use "tailor-made" ratios in order to make it perfectly adjusted to your specific rig. (for example, see here:
http://pool.hashrefinery.com/site/multialgo )
Is there a similar option with MPH ?
No there is not. You'd have to use something like Multi-pool Miner and tune the crap out of it.
