It looks like HashClash is developing a pattern of releasing a small amount of work 10k-20k workunits then shuting it off till they are returned (normaly in less than a day).

And everyone has caught on to thier scheme and are waiting to grab the workunits once they are available again. I was late catching the new release, but was able to grab a fair amount on a few machines, the other machines are starting to run dry.

I really don't like having to watch the clients this closely, got better things to do, but HashCash's scoring seems to be one of the better ones. More points per CPU/hr, which is always good.
