Wow thats a long time lol.well, i can give an outline of how long it took (with powerfeeding) to get my male to 3". it's up to you how you feel about powerfeeding though. i kept mine at roughly 82 degrees and fed as often as it would eat, until the 10/13 moult (which you can obviously see changed my results)
purchased 2/8/10 at .5" with an old moult already in enclosure
~2/8/2010 .5"
4/20/2010
6/13/2010
8/9/2010
9/11/2010 1.5"
10/13/2010
1/29/2011 3"
hope that helps
