Curious about leveling speed

[Arkista]

Going by my lodestone.
8/16/13 level 10 Beta ( played lots of different classes)
8/17/13 level 20 beta capped at level 20
8/24/13 early access started at 2am PDT ( I had a late start that day was in the PM)

8/25/13 level 30 ( I remember having a hard time logging into the game for two days cause of server issues 90k days lol)
8/27/13 level 40 (hit 100 fate achievement, 10 instant dungeons, 20 battle leves, 7 guildhest same day)
8/28/13 level 50 (bumb on a log achievement)

Catrum/Praet mapping was 8/28 as well.

All in all it took me 50-60hrs to hit level 50 with my FIRST job. Hope this is what you were asking for. I'm pretty sure there are people who did it faster than 50hrs.
