I'll register a new account when the current block finishes. If I understood DGM well enough, I could lose more BTC abandoning the current round than I have in altcoins...

I'm under the impression that you should have no reason to think like that. In a fair payout method, all shares should have the same expected payout, and not depend on history at all. With DGM (and most other methods as well), the actual payout per share will have lots of variance, but it should average out after a long enough time, even over multiple accounts that are mining only occasionally.

DGM is really hard to understand, and unlike with PPLNS, I still haven't grasped it well enough to be 100% sure of the above. However, it would be a very lousy payout method if miners were forced to stay on the pool to not lose their expected payouts.

as I understand it abandoning a round at any other time then "very near the start" could infact drastically reduce your payout. Which is why I've argued so much about the switch. I'm off mmpool (for good I think) finally as a result of vircurex going down I don't really feel like recreating another dozen worker accounts to reset addresses.


I would really like to hear some proof that DGM indeed works that way. I don't feel 100% confident that it's fair in that case, but haven't seen any real proof that it's not, either. It might definitely feel like you are losing expected payout when abandoning a round, but unless you have proof that DGM works that way, I'm more inclined to believe that the opinion is just based on a misunderstanding.

The huge failure of DGM is that it's almost impossible to understand (I mean really understand, not just on the "capacitor is being charged" -level Smiley) if you aren't a hardcore mathematician. I'm far from that level myself, and thus Bitparking doesn't feel as attractive anymore. Then again, even if you can understand a pool's payout method, it's another thing whether they have implemented it properly...
