I'm at the bottom of my neck now (is that really a length? Lol). I just measured and I'm 6.5" from APL, and 4" from that point to BSL. So that's 10.5 more inches, right? With my current growth rate of about .75" per month, that's another 14 months? So that would be 17 months from my TWA, with no set backs of course.
I'm just gonna round it up to 2 years.....I always need a cushion lol.
