Making sense of dialogue options.

[SnigTheAxe]

Could anyone help me understand these numbers that appear beside specific dialogue options that are tied to my skills? For example in this picture, the "Bluff" option has the number 3 beside it (as do intimidate and streetwise). I can't figure out what those numbers represent, because when I highlight the option the shown number does not correspond to my actual skill or my party assist, as far as I can tell. As you can see my bluff should be 5. One 1 from my and 4 from my party assist. So why then does it show 3?

I would assume it represents the required points for the dialogue

Indeed. That's the minimum skill you need to unlock those dialogue options. If you don't want to see them you can hide them via the game options menu.
