I was checking my intonation and it was a bit off and after fiddling around with it I think its pretty good now, all the notes at the 12th fret are within 10 cents of their notes, is this good enough? Should they be closer? Maybe 5 cents or something? At lest to my ears they sound pretty good...
Within 10 cents should be okay if it sounds in tune to you. Equal temperament is out of tune anyway; so go by your ears, not the tuner, when it comes to fine-tuning.
