After I wrote that a bit later I realized it might have sounded accusatory or advasarial and I apologize for that.
Apoligy accepted Smiley

However, the contention in the message still stands and I'm not seeing where there's a rebuttal in so far as providing anything to refute the fact that you simply aren't reporting the stale/invalid shares even though they exist.  
I don't really understand what you mean by not reporting them. Sure, our statistics are pretty basic now but the valid/stale/invalid counts that we have been reporting are (1) reflecting the share submission results we returned to mining clients and (2) accurate. (1) can be proven by miners themselves, if they keep a detailed log of sharecounts. (2) is never provable I guess.

(...) whether or not you report it is immaterial to the fact that you are paying for stales - you pay for them either way, so it is to your advantage to NOT report them to give the illusion that you have a better (lesser) reject rate than other pools.  
That's right. There definitely is a reputation incentive, and not a financial one. Non-PPS pools have both.

I'm not sure you understand how LP works when talking about stales in relation to LP.
We rewrote every line of code that had to do with LP, because it was horribly inefficient, so I understand a thing or two about LP. However..

It's completely immaterial how connected your bitcoind is or how quickly your bitcoind gets notified of a new block
you're right about this. My mistake. In NB2 I should have written 'invalid block' where i wrote 'stale'.

(...) you've found some magical new method to a) reduce latency between your getwork server and bitcoind by a factor of two or three and more importantly b) found a really magical method to notify all miners of new work with less latency by several orders of magnitude.
There's nothing magical about it. Deepbit is also quite good at it as I understand.

On a general note, thanks for your inquisitiveness, it's good to ask the hard questions once in a while Smiley. I really do want to focus on improving ABCPool now, so I won't be giving this kind of detailed replies any more on this topic.
