Not 100% true. It's correlated to ticket price, but in a different way depending on the type of fare (eg, Wanna Get Away vs Business Select). In that the moment all Wanna Get Away fares are sold out, the points price suddenly jumps, because it's now using a different multiplier when the fare is coming out of the Business Select fare category.
