I'm pretty sure the science behind it has merit. I suspect (guessing is more like it) that what you are doing with that lobe shape is at a certain point in the lift curve (again, I suspect the cam grinder will have an idea where this should occur) where the lifters rate of lift is slowed down considerably to get the valve to spend more time between say .200 lift on the opening side to .200 lift on the closing side.
It's probably somewhere more like .400 lift if what I'm saying makes sense. You are effectively slowing the valve opening down at certain lift points.
