hi sorry for asking this question, maybe it has been solved in replies before, but or the moment everytime i tried to use the profit switching i was disaponted. probably because i don't master it enough

Here is what i tried recently
For my nvidia rigs, i like to mine ZEC in nanopool, where it s then easy to monitor, payouts are fast. However, zec is not always the best to mine.
I tried to set up zergpool, and payout in bitcoin, which means long time payout...
I've run off course the benchmarsk, and even remove ccminer to have for Equihash just DTSM.
Now, often, when i run the profit miner, it will mine ravencoin, and i let 2 rigs, one on ZEC, and one on the Ravencoin decided by Awesomeiner, both having same config and same benchmark.
At first, Raven is indeed better ROI, however, as the hashrate is not stable with X16R, value will drop, and at the profit switching window, even if the ROI is less then ZEC, it won't switch.
I did had pool for ZEC in the custom pool for the profit

What am i missing for it to work ?

Thank you
