Average points/unit are rising (check team history at fahstats). When the WUs that are being handed out suddenly shift to being bigger and taking longer to finish, one would expect the point rate to drop off until many of the team's computers have digested a couple and get spread out from each other in completing WUs. Then the rate should come back.
There are a number of FAH servers that are rejecting connections so that completed WUs can not be returned. I think I'm up to three of those (two for more than a week, one for today).
