When taking quartet coachings from Dr. Rousseau, he had us tune to written f#, thereby tuning to a P4th/5th.
Another way of thinking is the way string quartets play 'in tune'. There are no absolutes in tuning because of the Pythagorean comma vs. 'equal' temperment. It all comes down to your ears. IMO, even if you try to tune every note spot on with a tuner, you'll never play 'in tune' in all situations because of this.
