OK here's some obviously flawed logic of my own but I'm curious where the flaws actually are:
In a 0% fee standard proportional pool, each person is paid the same amount per share when the block is found - I'll call it just "Prop"
In a 0% fee PPS pool each person is paid the same amount per share (during a 2 week difficulty) no matter how many blocks are found - I'll call it just "PPS"
In a 0% fee DGM pool each person is paid, well, you work it out
- I'll call it just "DGM" - but it is apparently the same as PPS in the long run
If I were to mine Prop for 129 minutes and then mine PPS for 171 minutes with X GH/s where Prop has an average 300 minutes per block for 2 weeks, then I would receive an amount that is higher than mining PPS constantly (or Prop constantly)
Of course it wouldn't be 171 minutes PPS every block, but it would average out to that.
This is called hopping (I've got that right?)
i.e. although I would get paid the same per share that I mined as anyone else who mined on Prop, that is considered "unfair" because although it is quite logical that each share should be worth the same since you spent the same amount of effort on it as everyone else with the same hardware setup, I still get more than expected for my X MH/s due to the mathematics involved.
"fair" seems to be that if you leave early your shares are worth less per share than someone who stays, since this stops you from getting more than your expected payout for your mining X GH/s
So yeah the first part seems odd that you should get paid less per share than everyone else - to make it "fair" so that you don't actually get more than the expected amount for your X GH/s
Logic fails, maths wins.
Now, no matter how you word it, when someone is mining PPS they get the same amount.
When someone is mining Prop they get different amounts that adds up to more than the PPS rate ... otherwise there would be no point hopping.
If on the other hand, they did the 129 minutes on DGM and 171 minutes on PPS they would still get the same amount from PPS.
However, DGM resolving: "hopping getting extra", means they MUST get less than mining Prop thus they must get less per share than mining Prop, thus they must get less per share than everyone else mining DGM.
How does DGM ensure people who hop will get less per share than the people who don't hop?
Why doesn't that happen to anyone who doesn't mine 24/7 but say instead mines 2/3 of each day? Or does it and that process of mining only 18 hours a day means they would get more on Prop than they should, if not for DGM?
Yeah that's actually some questions also ... if anyone feels like explaining that so that others who use DGM and didn't do university level statistics can understand, that would be good
(and also point out the flaws in what I said)
