In response to AtLarge: without quoting your entire assessment of the Poolology book, I'll quickly reply to a few of the issues.
First off, you provided a very good, honest, and accurate assessment of the system's limiting factors and benefits.
The actual aim point difference between a 3/8 and a 1/3 aim is 0.09" at the OB. The offset angle (angle between the alignment line and the aim line) is close to 1° from full table distance on a 9' table, and around 5° when the CB is within a foot of the OB. This offset changes the actual cut angle of the shot by half of the offset.(a 30° cut from one foot away ends up being a 28° cut, while from 7 feet away it's a 29.5° cut). This offset angle climbs significantly faster as the CB gets closer to the OB. So when the balls are closer than about 8", the offset is already bordering approximately 10°, which means the a 30° cut angle will come off at 25°, too thick unless you're shooting into 5.5" bucket pockets. A thinner aim must be used at close distance.
This info was added to the book about a week ago. My apologies for not including it before then. I wanted to make the material as simple as possible do I excluded some of the finer details.
Thanks for the review. It's pretty much spot on. Oh...the reason the cover shows a 1/2 ball shot with a non-1/2 ball angle is simple: I made the image in windows "Paint" and the 30° line was jagged. Lol. So I moved it to where it looked nice. You are the only one to notice it, or comment on it! And I thought I had gotten away with it! Lol
