Although I've read alot of post about wounded deer you'd be supprised what the actual numbers are. If you interested in a good read check out the link below to a study done at Camp Ripley

Although you may read a number of post requesting help in finding a deer the percentage of deer lost to bowhunters is actually quite low. Although I agree with your rules 1,3 & 4 and 2 for a beginner there are instances when a shot other then broadside are acceptable. A quatering away shot for instance gives you plenty of access to the vitals.
Whoever gave you that list has definately got you started in the right direction. As you develope as a bow hunter and gain experience you learn what you and your equiptment are capiable of and be able to refine you "game" more. I've been at it now for 12 seasons and I still am learning.
