As a middle ranked amateur league shooter (APA) and someone who shoots in pool halls and bars a lot, this website is INVALUABLE towards removing the unprofessional and not true witchcraft tips people give. Once you get into the slow motion of videos, or for example the same author tested a slew of other variables people to claim make a difference, he concludes that many of these things are just not proven and not true. Example is: what chalk to use on a shot. He tests and find it does not matter, as long as one applies chalk correctly before each shot (should be second nature). Pool is a game mostly taught by more experienced players to less, and so a lot of things are wrong or passed down incorrectly. Sometimes even people will be correct, but for the wrong reasons.

Slo-Mo shots are great for explaining things like "double taps". That's when your cue contacts the cue ball twice while following through. It happens in situations where you are followng through into an object ball at a close distance, and so the cue ball bounces back into the cue while the cue is moving forward, giving two taps. this is an illegal move and results in a foul in most play besides casual bar rules. Showing someone in slow motion, it makes a lot of sense.
