Mining for deepbit.net.
They have pay per share, and proportional to choose from.
Which is better for high end GPU?
and which is better for CPU? or low end GPU?

You can help me to improve PPS/Prop description on the site - tell me, what should I change to make it more clear ? :)

Choose PPS if you want a bit lower, but very stable income or Proportional if you are feeling that pool is at normal or higher-than-normal luck.

so you are the same person i chat with last night?

So if the pool as a whole have lower than normal "luck" when compared to the entire BTC mining community, I will get lower BTC if choose Proportional?

This is what I am understanding:
1. When the pool operates at normal to above normal luck:
PPS gives lower BTC, while proportional gives higher BTC.
2. When pool operates at normal to below normal luck:
PPS gives higher BTC, while proportional gives lower BTC.

Did I get that right?

Does how powerful a CPU or GPU change the above facts?

What if you put a simple calculator on the site somewhere, have a user enter their average mhash/sec value, and have it compute based off the pools statistics over the last 24 hrs, how much you would have made running PPS or Prop.

The current explanation is ok, I just think people would like seeing some estimated figured for either choice based on their performance.

It's the most asked question ever :)

About the calculator - using "last 24h stats" is wrong because future results do not depend on past ones, so luck can be -15% all the night, but then instantly turn to +15%, for example.
It may work as "sample values", but people should know that they must not make decisions on PAST data.

Yes.

Not compared to the community. Luck should be measured by comparing average number of shares per block to current difficulty.

Yes, but...
1) Luck is different for each round.
2) PPS income is the same in both cases.

No.

Yes, I know the actual PPS stays the same in both cases.
But I am comparing PPS payout to Proportion payout.
So when PPS is COMPARED to proportion, PPS is lower when the pool have good luck. And PPS is higher when the pool have bad luck.

Yes I agree estimates based off the last 24hrs would not be accurate for prediction. As long as it is clearly stated that calculations are based off past conditions, and explain how those conditions change very rapidly I think it would still be a usefull bit of information to newcomers to your pool.

Either way, I'm sure individuals will elect to try both for a while and decide based on outcomes..

How exactly do you change between the two, by the way? I couldn't find any related option under the account options.

Mode can be changed separately for each worker on it's properties page.

Ah, I see.

Which one would give better results with a single 6950 (~300mhash)?

Oh, not again :) Please, read this thread and tell me - what exactly is not clear in the description ? :)

It doesn't depends on your speed. You choose between stable income and luck-dependent one.

Haha, sorry.

Guess I'll just run it the other way for a day and check the stats.

Yes, but you should remember that the luck can be different each day :)

That's why I said a day, not a few hours or so.

Actually a whole two weeks can be more than 15% off.
It's normal for days to be +-30%.

I remember doing between 2.6 - 3.3 btc a day with proportional, if PPS gives me only 2 or as much as 4, then I already know which one is more advantageous.

Im the opposite, with my single 6990 i get almost double PPS than i did proportional :)

Normally if they have it structured correctly, proportional should pay more over longer timescales, because pay-per-share ordinarily requires a higher pool fee to compensate for potential bad pool luck.

Another aspect to the story is that if this is a straight proportional, that might be undesirable if you intend to mainly just mine there, because proportional arguably can incentivize pool hopping (i.e. you switch to a pool the moment it solves a block, so that if another block gets solved quicker than you would expect from chance alone, the shares you've contributed to that block are relatively more valuable). If their proportional is a PPLNS then that notion isn't a concern.
