Why is this marked as Rev 1?

What part of this tells us it's a revision? I don't see an original dump anywhere, and I don't see anything in the missing games list.

Why would a sample of the game make the first original version the Rev 1? I don't remember that being a convention.

Earlier executable build date.

Respectfully, that... makes no sense. This is just simply not a convention we have.

007: The World Is Not Enough (USA)
Beta (2000-08-25)
Full release (2000-09-22)

Adidas Power Soccer 2 (Europe)
Demo (1997-07-28)
Full release (1997-09-25)

Alundra 2 (Japan)
Taikenban (1999-08-27)
Full release (1999-09-25)

3 different games, regions, and pre-release types. EXE dates are all later for the full release, none of them marked as Rev 1. I didn't even have to go very far for these either, these were on the first page alphabetically. This is just not a thing. We don't mark a game as Rev 1 if it's the first full release of the game. Unless that's a new convention and literally everything needs to be changed?

Again, sorry if I'm coming off as snarky, but this is really confusing me and I'm being given weird reasons as to why Tekken 2 is being marked this way and like... nothing else follows that convention. Just trying to make sense of it.

EDIT: Is this a thing that's very specific to versions marked as "Sample" ?

EDIT2: If it is, this one is wrong.

Riot Stars (Japan)
Sample (1997-02-26)
Full release (1997-03-02)

Tekken 2 (Sample) is a full release game, not a beta, demo or trial version.
The edition of Riot Stars may need to be changed. (For example, "Sample Version")

Usually, the sample edition matches the original.

Tekken 2 (Sample) is a full release game, not a beta, demo or trial version.

When I looked for other "Sample" editions of games, I found that most of them were lumped in with a dump of the original, so this seems to be the case. That's why I'm wondering if this is only a thing specifically with "Sample" editions (that is, calling the first commercial release "Rev 1" because the "Sample" that came before it is different).

The ps1 sample almost certainly has a matching retail release with the same build date (it just hasn't been dumped yet).

Another similar case, the promo likely has a retail release which hasn't been dumped yet.
