I’m just going to say that you can’t make a big, one size fits everybody statement like “You will not grow if your extender isn’t set longer than your BPEL”. Someone will. And my instructions with my extender said to go 1/4” less than my BPEL for my first week, and I did, and I gained 1/4” in erect length in that week. And the next week, and the week after that. I suppose it was the theory of “less is more” as it applied to extender length. I goofed, completely forgetting to add any more pieces to the extender arms for my first 3, possibly 4 weeks. And I gained and gained and gained. Got a total of an inch and a quarter in length in my first 6 or 7 weeks.
