Carb Cheater 2.0

[Coelacanth]

I watched this video last night. Disregarding the Carb Cheater, what do you guys think about the carb adjustment he demonstrates, about seating the carb mixture screws, then unscrewing them 2 full turns (I believe with an Edelbrock, the recommendation is 2.5 turns out), then using vacuum to tweak the amount of lean to the car to reach the highest level of vacuum? Then I believe he richens it a bit after that, 1/8 to 1/4 turn out?

That's the standard operating procedure. Holleys generally start at 1 turn out.
