What's the Rocket League punch to practice 10k times?

I'm back to play Rocket League after a hiatus (I'm p3 in 2s, my peak was c3 years ago).

You may have seen the Bruce Lee quote about fearing the man who practice the same punch 10000 times instead of 10000 punches.

For fun I would like to practice one thing 10000 times and see what happens. No bakkesmod.

What do I mean by thing? A shot? A skill? A sequence?

I want to keep this open to your interpretation.
