drilling a hole in the back of your scoop?

In my twin hood scoop thread someone said this:

every 8" you want to drill a 5/8 hole along the back of the pan to let dead air escape because otherwise you carb will be drawing from partially stagnant air thus eliminating the effectiveness of the scoop.

Anybody have an opinion or info on this subject?.......Or even a link to a theory of this subject?

I have seen big scoops with holes in the back of them......Assuming that they were for gauges like fuel pressure temp exc. Maybe they were not?............
