The only thing I can offer to the debate of the CPS and strong spark is that it would seem one of the tests for the CPS would involve checking the spark at the coil in the manual which I dont believe it does or perhaps its considered slightly dangerous. Perhaps more often than not, a strong spark is indicative of good CPS. Thats all i can add which obviously is not much. I do appreciate the comments here; hopefully this thread will be of some value to others if we can come to a definitive answer. Thanks guys for trying help!!
