Is anyone else seeing some strange data in the estimated reward and their current scores? I have a current score of around 6000 with over 8700 shares and my estimated reward is about 2% of what I normally see for the same number of shares. My hashrate appears normal.

Any ideas or explanations?

With a very modest hashrate (about 7.5 GH/s split evenly between Slush and BTCguild) I see large variations in Slush. This seems to be due in no small part to over-aggressiveness on the part of Vardiff: it appears to go in cycles over about 20-30 minutes, dropping from difficulty 4 to 1, then up to 2, then up to 3 or 4, then back down to 1, resulting in big swings in the estimated reward. BTCguild, meanwhile, remains steady on the minimum of 2. Sod's Law decrees that Slush will often solve a block just when the estimated reward is at its low point, resulting in variance of over 50% even on reasonably long rounds when one would expect some consistency.

It seems to me that Vardiff is too sensitive to sort-term changes; while this may be a useful attribute in the first few minutes after establishing a connection, it becomes a liability once the worker has settled down.

Maybe vardiff needs to tone itself down after N shares or X minutes of runtime?
