You sound silly, as if you've never shot a 40.
Because there's an energy gauge on the gun?
If you meant "have you fired a .40? The increase in felt recoil and muzzle flip clearly indicate to me that there is more muzzle energy!" felt recoil and muzzle flip are the function of a lot of things and the primary determinant in them isn't energy.
They in fact do. You should go compare some handloading manuals, a variety of manufacturers of ammunition online or even the wikipedia page on the two.
I'm sure in real life you're a perfectly nice guy, but on the internet you use willful ignorance and garden variety ignorance to craft your arguments. It's hard to have a productive discussion with someone like that.
If I had to compare it to anything else, it's hard to debate the importance of the calculus underpinnings of multilinear regression when you're a trained stastician and the person you're talking to can with difficulty do some algebra - you know some of the language and you've got an opinion, but it's an opinion based on what you don't know that you don't know..
