I was wondering if there is something that can be done to get a more consistent hash rate on P2pools (I would insert images to show exactly what I mean, but it seems as though I can't upload images to the forum so hopefully my description will be sufficient).

When looking at the graphs over a 24 hour period my hash rate oscillates +/- quite a bit.  When looking at my graph over the period of an hour there are times all over the place where it reports I have 0 hashes/sec. 

From looking at other peoples graphs it looks like there are a lot of people in the same boat, but there are always several people who get nice consistent graphs which never show 0 hashes/sec.  I was wondering what causes this, and if there is a way to keep a consistent reading for my hashes?

I have double checked that my GPU's are stable. I also have multiple machines going so I would think one would always report some hashes and not give me a total of 0.  I've also wondered if this isn't a latency issue with the pools, or the network?

Any help, info, or answers would be greatly appreciated.
Thanks.
