Actually, I've been timing my bow limbs since early on. It just made sense. I didn't have a thorough understanding of it back then, in fact bows still hold many lessons for me. I tried to fully comprehend everything Dean was talking about, but it just took me some time, experience, and experimenting of my own. Early on, the main thing I was trying to do was build a bow that sent an arrow without porpoising, built-in good tuning, because I reasoned that was a bow's entire reason for existing in the first place... to shoot an arrow well, but eventually I learned it was much bigger than that.
