almost right, except the shift simply finish when enough has been mined and exchanged. If there happens to be a big spike in hash rate, the shift will end sooner. For now, until I can see there is a steady and consistent hash rates, the shift are manually ended when I see enough has collected for it.

Ideally I'd like to pay all algos, each day or even twice a day. But for that,  there needs to be at least ~3Th SHA256, 125Mh/s Scrypt and 2GH/s X11 consistently.

Not quite there yet, but I see scrypt just blew up and it's running ~310mh/s

Also with more coins to exchange more often, it allows a more consistent and plentiful DRK buying on the exchanges, pushing the prices up.

Which is good, but also, need to realize that it's going to make the payouts slightly less. Kind of a catch 22, but I think the end goal of a higher price is worth it.
