I haven't worked out the details yet, but I'm going to be moving to a proportional-like payment system soon.
I've been thinking a lot about the current payment system lately, and I think it's partially to blame for the low profitability. The amount the multiport miners lose out on paying the dedicated miners right after a switch is never made up for on the other end after the multiport leaves that particular pool. In order to make up for this, I'd either need to move down to an extremely low round time (e.g. 20 seconds) or make the round much longer.
For now I have dramatically increased the round time on many coins in an attempt to spread the rewards more fairly. I've also increased the amount of time that the Multiport will stay on some coins before moving off.
Litecoin: 24h
FTC, NVC: 6h
DGC, WDC, CGB, MNC: 1h
I believe this should increase profits for the multiport miners to more closely match the calculated profitability.
No quite sure I like this. Digicoin frequently pops to 1500% bitcoin for about 2 hours. This could be missed completely if mining LTC, FTC, NVC.
I don't see why you would have to go more than 2 hours static on a coin.
Personally I will not get caught in this trap. Manual mining for now. Quite happy manual mining CGB at the moment.
