Standing ovation!!!
The image is fantastic, and I really appreciate the description of your process.
I tried with 30 second exposures but only got 2 meteors:

I have the theory that the fainter meteors can be washed by sky glow in the long exposures so maybe your 4 second exposures does the trick. What do you think?
