The article states this:
When lowering the weight, keep it under control. If you needed to stop and push the other way you could. Donít artificially extend the time youíre lowering it.
For the concentric portion, taking the bench press as an example, when the bar is at your chest, imagine trying to push it forcefully, like shoving someone away. It wonít actually move like youíve pushed someone off you, but as long as the intent is there donít worry. This will feel quite different if you donít already lift this way.
I want delve into that subject just a bit more, to see if what I'm doing is relevant or not...
I read somewhere on WBB a while back that there is a benefit to be realized by not pausing between repetitions. To simulate a pumping motion during the set. No rest at the top.
True? Or not something to worry about so much?

personally i wouldnt worry about it. i vary honestly, and not due to a concious preconcieved intent. My lighter warm ups i tend to flow right thru the reps. As I get heavier it slows down =].
There is a benefit but performing any exercise this way is going to necessitate a reduction in load or reps (with the same load) because of the increased fatigue.
The aim in our program is to use loads that recruit all motor units from the first rep and fatigue the appropriate ones with the clusters. Reducing the load or reps would change the focus more towards fatigue as the stimulus for growth.
Tension (higher the load higher the tension) is the primary stimulus for muscular growth with fatigue required but secondary which is what our program focuses on. That's not to say you couldn't adapt this program using those techiques, but it would shift the focus. If you decide to do that please keep me informed, I'd be interested to know how it performs.
