I try to follow the main page programming. I have a policy that I can't move up in weight until I improve the previous version of the WOD. I use CrossFit Brand X scalings and if I set a PR, I move up to something closer to RX.
BrandX typically will tell you the goal of a particular MetCon. For example, they'll say that you should be able to do Fran in 5-7 minutes. If you're below that time, increase the weight up to RX. If you're above that time, decrease the weight. Your goal should always be to complete the WOD in approximately the same amount of time as top athletes, you're just doing it with less weight.
Lots of good information in the BrandX forums around scaling and measurement.
