So sorry for the mistakes! I went through the same confusion with some conflicting advice from two different sources when I was starting out. I've been thinking about changing it but in all honesty, I've been too lazy. I've really just been a bum the last several months and haven't done anything but sleep and rockclimb occasionally (one of my other hobbies). With that being said, don't take everything I, my book, or any other source of information, as being 100% correct. Not only can there be typos, but information changes over time and certain information can either be disproved or updated to something better. If you ever feel like something is not right or could be done a better way, just ask! Because you might turn out to be right
The pdf in this thread is only the 25 page one I think, not the 50 page one on amazon. Here's the pdf of the one on amazon, I only charge for the physical copy so feel free to share this:

Again, if you feel like something is incorrect, just ask someone. I haven't look at it in a looong time. I had to sell my entire lock collection a while ago and haven't had any locks, key operated or combination, for far too long..... Although, funnily enough, I just received an audio amplifier so I have a pretty nice amp but no lock to use it with!
