New Book for Animators / Digital Artists - Beyond Tiki

Does this book cover PROPER green/blue screen lighting or do you know of a resource that does the subject justice? There are a lot of contradictory opinions on the subject and more general blather based on how someone was taught versus knowing precisely why something is done or not.. I've gradually moved to lighting my backdrop 1 to 1 1/2 stops below that of my subject as measured by an incident meter since both waveform monitors and reflectance meters are color biased to varying degrees depending on their manufacturer and don't provide accurate readings for a camera pointed at the screen. This seems to work out okay, but I'd like a scientific application of lighting to optimize keying possibilities. Maximum color saturation should occur at 50% brightness (55 IRE) but does it? If I expose the screen for middle gray everything else should fall into place right? Wish I knew for sure. Feel free to move this to PM and then email so as not to have a wildly non-tiki thread.
