It's what I read from other people's tests. I didn't attempt trial and error on the same check to make sure myself.

However, I have seen checks fail with 3 persuasion, and succeed with 2 persuasion and higher relevant stat.

It could also be that persuasion lowers the threshold, by an increasing ammount.

The wiki suggests that persuasion could also be a multiplier, which would explain quite a bit too (especially if the increase is not linear).

Still, there is only 1 way to check for sure:

1 - Edit a character down to 1 or 0 in the relevant stat (with 0 persuasion).
2 - Increase the relevant stat until it's possible to pass the check.
3 - Add 1 persuasion
4 - Lower the stat until it is no longer possible to pass the check

If at step 4, lowering the stat by 1 fails the check, you are correct that it is independent from the stat. If it does not, then it is not independent from the stat (unless it doesn't fail all the way to 0, in which case you will need to test at a more difficult check).

More easily done with a cheat in hand to propperly edit stats.


EDIT: Keep in mind that some persuasion dialogue options are impossible (Tiger in act 3 is an example, but on this case all are impossible, sometimes only 1 option is) and some persuasion dialogue options are impossible to fail (almost always clear if you're paying attention to the conversation). This needs to be tested on an option that can both fail and succeed.
