They are indeed, both facts that YOU refuse to accept.

1. Some .45 bullets do have larger meplats than some .44 bullets. Some do not. For the millionth time, it depends on the individual bullets in question.

2. It is a fact, pressure is irrelevant. What the .44 does with slightly higher pressure, the .45 does with more powder. Net result? The same. The pressure difference is meaningless.

You act like I haven't read all that Linebaugh stuff, numerous times. I've linked to it, numerous times. Long before you ever came into the picture.

Some .41 bullets do indeed have larger meplats than some .44 or even .45 bullets. A few from Beartooth are WLN's with meplats larger than a .44 or .45 LFN.
