It takes a long time to make sure it's stable. Also how stable do you want it to be? Some people want overnight stable, some want 8 hours stable. It really depends. If you want fully stable do it slowly over time. If it doesn't matter as much, then just do it in one go at +0.2 and making sure it's stable using 4~8 hour stress tests.
I would personally, do w/e you can achieve max and -0.2. That way it should be pretty stable and overclocked nicely.
