BACK to the topic of this thread.....  P2Pool...

I have more questions...

If i set my refresh rate to 100ms, at my low has rate (150mh/s) won't I never find a share because my GPU's don't have enough time on the current block to find any shares?
Doesn't the refresh rate REQUIRE a minimum hash rate to find any share or block?
What would increasing my refresh rate to say 1000ms do?
Give me potential dead/orphan shares? (local dead on arrival)

I have tried refreshrates of 100ms, 750ms, 4000ms, 8000ms...
If I go longer refresh rates (above 1000ms) then I will get lots of dead on arrival, but I find that my share # goes up.
 Some arrive as dead, orphans, but more show up as good shares.
If I set my refresh rate to say 100ms... I find that I produce NO shares, no dead, and no orphans, in a 24hour period.
If I set it to 750ms, I find I can produce 1 share every 4-8 hours or so.
If I increase it to around 4000ms I have lots of local dead on arrival, with even more shares than a lower refresh rate.  (but more dead and orphan shares show up.

I guess I don't fully get it all, but my understanding is that if you set the refresh to a longer rate, you might produce old shares.
But having some dead/orphan shares is better than none at all.    So it seems that people with lower hash rates should use longer polling?
They may get more dead, but at least they will get something.
 I found that not all were dead, only say 10% were dead when I had a polling rate of 4000ms.
So what gives, does polling rate depend on your overall hash rate?

What I notice, is with very low polling rates(100ms or less), I produce no shares at all.   Even if I run it for two days.
But if I set it to 750ms or longer, I will produce about 1 share every 4-8 hours.
And if I set it to about 5000ms, I will produce about 1 share every 2-4 hours(with 25% of those shares ending up as dead/orphans)

So does polling rate depend on hash rate, if you want to produce any shares at all...(dead/orphan/good)

Hi because of your low hashrate the P2P share chain (similair to blockchain of bitcoin) has already found new shares. You can see share difficulty on the website of your miner node. With the current difficulty of writing it gives you around 4 shares each day But you could connect to a public node of P2Pool (check the p2pool servers list) and connect to there. This will "give" you 1 difficulty shares if i look correctly (i see alot of accepted on my gpu's but not so much on the miner node) and this will count your count of the shares from the miners node and give a payout to your adress (use adress as username, and no password) Then you still have some variance, but its less Wink.

Its (if im right) some kind of proportional from the miner node wich mines at p2pool in PPLnS system  Cheesy
