Yeah, point creep is what happens when demand for certain tags exceeds the supply. Each year it ends up taking more points to acquire the tag. A real simple example: In the first year of a preference point system let's say 20 people apply for 5 tags, so 25% of applicants draw with zero points. In year 2, nobody with 0 points will draw because 5 of the 15 unsuccessful guys from last year (assuming they all apply again) will draw with 1 point. In year 3, there will be 10 guys with 2 points, and still only 5 tags. In year 4, the remaining 5 guys with maximum points (3 points in this case) draw the five tags. So in four draw cycles, the odds went from 25% to a situation where you need 3 points to draw the tag. That's point creep.
