My last couple of re tightenings have been at a 3 week interval, which takes long enough over a couple or so days. My fear is leaving it to 4 weeks and take forever to re tighten. I have noticed an incredible growth rate, granted from my crown area where all the density is on my head.
What's your rate of growth and where?
It had been five and a half weeks since I re tightened so as you can safely expect, it took me a wee longer to complete. I did them in 3 evenings after work. A lot easier to digest that way. All i remember thinking was that it was taking soooo long and i was getting bored.
