it also has to do with your height too. But yes, it's the hardest stage and I have yet to reach APL. I've been baggying and I know I will reach it before the ending of 2010.
-relaxer stretching (12-16 weeks)
-very little direct heat
-hair worn up/off the shoulders
-general PS (half-wigs, buns)
-deep conditioning....
Took me 9-12 months. (I give a range because at 9 months I was just at APL, but didnt feel like I made full APL until a couple weeks ago). Probably wouldn't have taken so long if I had been more careful about not falling asleep without a scarf (I'm verrrry guilty of that).
