Deers has it.
If we assume a 12" barrel, and a fast enough cycle speed so that the first ball hasn't quite left the barrel before the second ball starts to move, it's still largely irrelevant because the first ball is still subject to accelleration just like the first one.
If they're 11" apart, by the time the second ball has moved an inch, the first ball has exited the barrel. Yes, there are undoubtedly going to be a number of interesting aerodynamic effects with two shots that close together, complicated even further by the idea of any porting in the barrel, or whether it's a 2-piece stepped-bore, etc.
The first ball will immediately start being slowed by air friction once it leaves the barrel, but so will the second ball.
