Great stuff!
The differences in credit/second changing based on sub project definitely caused issues with the tables I made. Some of the hosts where super optimized and scored 40-50% higher than the next person. I knew that PrimeGrid was because of PPS-sieve. This explains what was going on with the Yoyo@home data.
I'm also working on a script to make downloading this sort of data from the project websites easier. I'm still trying to get it working with Einstein and Yoyo. Hopefully I can get it working for all projects by tomorrow.
