Oh ... ok, thanks for the advice, but I'm not sure I understand ... if the fretted note is 5 cents sharp at the 12th fret, are you saying I must move the bridge back 5% of the distance between the 11th and 12th frets?

Yes. Although it's not quite linear - the true ratio will change in the same as the way the fret spacing increases as you go down the neck - it will be close enough over that small a distance.
