Ryan, it sounds like we do agree on priniciple of not being over-bowed and the risk of developing bad habits. I totally agree with your points regarding becoming discouraged. Doug's original question was related to hunting weight. I suggested a maximum weight for a beginner to start hunting with not a minimum weight to start practicing with. I did not say a person should never start light for practice, but I was assuming (perhaps incorrectly) that Doug was going to purchase just one bow.
Can a person start with a hunting weight bow? Often times not, but it depends on the individual. This is the time to set macho aside. You list some great guidelines. Different people will have different draw weights that they can pull comfortably. I let a friend borrow a bow of mine to shoot. He was new to archery. I started him out with a 46#@28 since that was the lightest bow I had with me at the time (he has a pretty short draw but we did not measure it--he may have been pulling 40). He wanted to try a different bow--53#@27"--I thought he would be WAY over-bowed but thought I would let him shoot a couple of arrows just to try the different style of bow (longbow vs recurve). He is a strapping 20 year old army recruit. He could come to full draw, hold anchor and release smoothly without strain. He shot that bow all weekend and hit what he was aiming at. I was shocked. This it NOT typical for a beginner. I would not normally recommend starting that heavy for anybody, I am only pointing out that there are individual differences that dictate just how low a draw weight a person needs to start.
