Yes, Using the Master spell Harmony in a place like Whiterun makes you go from 15 to 49 in one use. At level 85-90 it would take like 8 times to get to 100 then eventually 9. Using the restoration glitch I can create potions worth over 1,500,000+ gold which gets an instant 100 so that is most likely the fastest.
