How many bps is too many bps..Technical Question

BTW, Kinda new here, Hello everyone :)

Hello. :)

Sorry, but you don't understand aerodynamics. A second object will not pressurise the air behind a first.

Aerodynamically, a second object could be slowed down LESS than the first because off the low pressure area behind the first. That's why racers, truckers, and people following too close behind RVs 'draft' to use less gas.

I've also 'drafted' behind a municipal bus on my bicycle at a speed of 60kph. But that's another story and I DON't recommend you try it yourself.

I understand drafting (and even if my bike has disc brakes, Im not going to draft a bus lol) and I know that would have a function out of the control bore of the barrel and after it leaves the barrel, but I am talking if both balls are in the control bore of the barrel, before stepping or porting.
