If you set up a fretless to play right on the line at the 12th fret position it will be flat by quite a lot at the 1st. You can't compensate for that error by moving the saddles. Because of your finger width, the registration point of the string on the fingerboard will be about 1/8" ahead of the centre of your finger. For intonation to be accurate as you go up the neck the contact point would need to get progressively closer to the centre of your finger intonate, in just the same way that the spacing between frets gets narrower as you go up.You can set up the intonation on the bass to have you finger 'behind the line' or 'on it', depending on your preference. Ultimately you're better off getting your eyes on the board and letting your ears do the work, but that might be a little in the future.
Set it up the way you like and go from there.
So if you insist on playing right on the line, you have to actually move the position of the lines. And that really needs to be a custom job to suit the individual's finger width.
