I breezed through the articles, but I do have a disagreement with the misfire scenario he focused on in the first article. If there are a lot of people at a launch and your rocket has a burnt igniter, why the heck don't you take it off the pad and go to the back of the line??? That's what I do, if there are a lot of people launching. Having said that, I don't always do it if there are half of the rods/rails open each rack, but if there are a lot of people, my rocket comes back to the truck and I re-prep it there, get back in line and start over. I guess there could be logical exceptions for really complex rockets, but otherwise, I think it is just good behavior to not hold up the line because your rocket didn't go. Chances are that if the rocket didn't fly, there was a prep issue (IMO, not a fact) and a fair penalty for that error is to go to the back of the line.
Also, if there is a new flier there having tons of issues, stop what you're doing and help them achieve success. 5 minutes explaining/showing how to put the Estes igniter in without having problems for a new person will speed it up for everyone. Then get back to doing your own stuff with the knowledge you helped out instead of just focusing on your own fun.
