I have also heard such nonsense and commented about single cams and hybrids earlier in this thread, in the very first post on the threadas a matter of fact. I think these kinds of myths are started by either the ignorant or by people trying to sell something.

You are shooting a high performance bow. Let's imagine for a moment that your bow is a high performance car... say a Ferrarri. Suppose it's running a bit rough, but still runsplenty goodenough to get you to work and back. It might be doing everything you actually need for it to do, but you could get the same work from a soccer mom's mini-van. You paid a lot of money for a high end sports car, so are you going to be satisfied with the car not performing any better than soccer mom's ride? I wouldn't think so. You'd want to have that Ferrarri tuned to the max and running right so you could be a screaming blur on the open road if you were so inclined.

So... why wouldn't you demand the same level of tuning for your high performance bow?

That's the big thing about high performance equipment that many people just do not understand. High performance equipment requires a high level of tuning and a high level of maintenance in order towring outall the performance you pay for. Extreme competition shooters, as you name them, know this. It's something the average bowhunter needs to understand as well. Until that understanding comes about, the average bowhunter would be just as well off - probably even better off and have more money in his pocket to boot- with an inexpensive entry level bow with so-so performance. Just my opinion, of course.

In answer to your question... I wouldn't know without checking out the bow and setupmyself, naturally, but I do have a very strong suspicion that the rocking you describe is attributable to the tiller being a bit off. You might have the bottom limb a little too stiff.
