      According to Joana's WOW Ebook he completed level 58 to 59 in 5 hours and 33 minutes. I leveled my Horde Troll Priest in 6 hours and 34 minutes and took various screenshots to prove it.
     And based on a leveling experiment me and a friend started today at exactly the same time (Hellfire realm was down, so went on a PVP realm for the 1st time) I’m not that fast at leveling: The two of us started a new Horde character at the same time/same realm and are both following Joana's Blood Elves 1-25 leveling guide
   I highly recommend the this guide, the video is a must see for any WoW fan.  Joana/Mancow is no doubt the fastest world of warcraft power leveler, and can beat any farmer or even groups of people who take shifts playing.  This is the same guy who won the leveling contest last year, and he won it by a pretty good margin.  Check out his site for screenshots and movies.
