It might take 17 mins if you've spent the time to memorize every aspect of the dungeon. I guarantee nobody has ever walked into AV on their first try with party members who are no more familiar with it than knowing where the af is, and complete a 17 min speed run. Anyone who's done a 17 min run has had plenty of practice on it first, or went in there with 7 other people who have. I, and the people I usually play with have not spent the time learning that dungeon. Now, you can continue calling a lack of experience a lack of ability, but two are definitely not the same.
