That is a really good Idea. I am with you
Might as well get started!
NP -- "Normalized power." This metric attempts to answer the question, "how hard could a rider have gone during a ride if he had ridden at constant power?" For a typical ride, this number will be larger than the ride's average power.
VI -- "Variability index." Normalized power / average power. A measure of how variable the rider's output was during the ride. Rides with large VIs included highly variable power output. Rides with VIs near 1 were very steady.
IF -- "Intensity factor." A NP-based metric intended to represent the intensity of a ride (or section of a ride). To enable cross-rider comparison, the IF is normalized to a given rider's "threshold" (approximately equivalent to a rider's maximal 1 hour power). A ride done right at threshold has an IF of 1.
TSS -- "Training stress score." An IF-based metric that attempts to quantify training stress. By basing the metric on IF, it avoids the pitfall of most other measures of training stress (miles, hours, altitude gained, etc.) by accounting for the increased stress of higher intensities. A 1 hour time trial results in a TSS of 100.
For the entire constellation of NP-based terms, and how they're computed, see

SST -- "Sweet spot training." Training that emphasizes a high volume of the high end of what most cyclists think of as "tempo" pace: Zone 3 for Friel, Level 4 for Coggan, or "no man's land" if you're a skeptic about SST! The case for SST is made here:
