I'm still looking through how to handle outliers in the statistics. The point about overclocking is one of the reasons I chose non-K processor types for intel. On further thought I'm reconsidering whether I should have used the X parts from AMD since they have less overclocking headroom.
The real point of this is to tell you which projects you should look at running beyond the normal advice of picking a project with low team Rac and low total users.
For example, Yoyo has a fairly high Team Rac for a CPU project and a decent number of users. However if you are running a CPU that is from ivy bridge or later (or Zen) it is a good performer across the board. This is probably due to the project not actually having much dependence on the processor frequency.
The tables also show that if you have a high core count CPU you should switch to sourcefinder (can claim more work proportional to # of threads), YAFU, or Yoyo. Which is not something that a new user is going to know.
