I noticed that too (the pretty rapid acceleration), and you could be very correct about that selfcorrecting effect. Some older car carbs do something similar in how the air ducting is arranged, although most still had an acceleration pump.
Then again, it could also be a lucky strike with differences in the individual runtimes of the servo's.
A nice test would be to use a very fast servo on the air bypass valve, and see if you can affect acceleration behaviour by affecting the runtime of the bypass-valve servo. Not so much "improve" but to determine if there is a relation between the speed of the bypass valve servo and the acceleration behaviour.

Regardless of that, I really am impressed, and looking forward to flighttesting.
