The post feed describes the string track on the cam. Instead of being one long machined groove it's a series of machined posts that make up the track. Nock travel is not level but it's certainly not untunable. From the design of this system they gain speed less shock and their own patent, which is also licensed to a few other companies. I'm not in any way experienced with the Pearson cam so I can't give info on it. Hope this answers some of your questions.
