Looks like people are still confused with two existing reward distributhing modes, so now i'm working on third one.
Hope you'll like it.
I kind of wish it would automatically select the option with the greatest payout based on your hash speed, although I suppose that would be less than ideal for the pool.
My guess is that while if you are on the extremes of the speed it is easy enough to figure that out, but for those around the middle, it can be difficult to say which is better.
there is no way, no matter what hashrate you have, to automagically switch to
option with the greatest payout,
except maybe if you own a time-machine, but i guess then you would have better stuff todo with it anyway.
hashrate (and from extension, average amount of shares of some time) and figure out how much you can expect to make in the long run using the different payouts.
