I think that you’re still confused about the Oberth Effect, and don’t intuitively understand it. But good news! I didn’t either, and you’ve made me confused in a new way, which is valuable. Since this post has pretty low karma, I’ll give it a weak upvote. But it needs to either: be renamed to reflect that it is a dialect with an uncertain ending or be polished into a correct intuitive explanation so clear that with a bit of thought, readers will realize why the other frames are wrong.
Also, typo:
If you increase the muzzle speed to 2 km/s, the bullet will be going at 2 m/s.
I’m still confused about some things, but the primary framing of “less time spent subject to high gravitational deceleration” seems like the important insight that all other explanations I found were missing.
