I personally think CJ's message is clear and simple and easy to express in words. How does this sound:
When English isn't required for CB positioning or throw, aim to undercut shots by half a pocket (by targeting the point of the pocket on the undercut side) and use a small amount of inside English to create squirt (and overcut) back to the pocket's center.
This will work well for some people, and it might not for others. The success will depend on accuracy of the off-center aim, exact amount of English, shot speed, cloth conditions, distance between the CB and OB, distance between the OB and pocket, pocket size, and shaft endmass (which determines the amount of squirt the cue creates). Some people don't care about these details and can still get the system to work in all situations. Other people like to understand how and why a system actually works and want to know when it might not work (without adjustment, either consciously or by feel).

This sounds ok but I believe that some of the success of this system is due to a certain amount of skill that beginning and intermediate players may not yet possess.
That doesn't mean that the technique isn't valid. In this particular case, it just means that the student isn't ready for the teacher just yet.
