One thing I think missing from your guide is that a flop shot is pretty much mandatory if the lip of a bunker is going to be an issue. Flop shots have the highest trajectories, as far as I can tell. Of course, you're sacrificing the ability to hit the ball more than 40 yards or so, and the shot is extremely imprecise, but if you think it's the only thing that's going to get you out of the bunker, then you have to use it.
The only thing that I've caught onto in my short time here that I consider to be somewhat secret info is that if you have a club that hits, say, 24 yards nominal on a chip shot, it will actually hit more like 28 yards if you hit with full power. If you hit with 50% power, though, it will go about 11 yards, and if you hit with 33% power, it won't go 8 yards, but more like 5 instead.
The same goes for hitting my wedges 50% power or so on a "full"-type swing. If I need to hit the ball 40 yards, and my wedge is rated 77, I'm going to hit it more like 45.
A common mistake people make, which you, of course, mentioned in your guide, is only paying attention to the up or down arrow marker on the hole, without taking into consideration the slope of the green. It's not just a chipping and pitching thing, though. Even on 100-230 yard approach shots, I look at that stuff. If it's 3 ft up 5 yrds before the hole, and it's 2 ft up 5 yrds past the hole, I know, then, that the green is sloping down, away from me, and that the ball is going to roll far, so I'll hit it maybe 2 or 3 yards short... even up to 8 yards short on Oakmont #1. If you keep rolling 10-25 yards past the hole on your 50-200 yard GIR shot because you don't pay attention to it, you will pretty much never birdie. Screwing up distance is the worst thing that you can do. It doesn't matter how much I mess up my aim click, I will never be more than 5 ft away from the hole after a 100-ft putt, and I will never be more than 10 yrds from the hole after a 100 yrd approach shot. There is no "getting lucky" with 20 yards past the hole on a 100 yard approach, or 20 ft past the hole on a 100 ft putt.
