Many apologies for the problems here. I was trying to ensure work unit availability for a smoother transition post-bigadv; in retrospect, it would have been better to accept a "gap" period for many-core-optimized work units and make sure that the rollout process worked properly.
What happened here was the following:
1. In benchmarking the work units, I mis-combined formulae and ended up with a k-factor that was substantially too high.
2. The very high bonus values that resulted triggered a safety threshold in the stats code, resulting in no bonus points at all for some work units.
3. We had a hardware failure on one of the benchmarking machines, slowing correction of this process.
We are in the process of fixing all three of these. Once these are done, we will proceed with a slow beta rollout.
Be advised that PPD values will be lower--they were inflated substantially by the benchmarking mistake I made. Many apologies.
Oh dear, I wonder what the new ppd will look like?
