101 of 101 carry a public description; Steam withholds the rest as spoilers.
Median playtime is the median total hours these owners have in Left 4 Dead 2 — not the time the achievement itself takes, which Steam publishes no way to measure. It says what kind of player holds it: the rarest rows are high largely because completionists play more. Median rather than mean because playtime is heavily right-skewed, and measured across 628 sampled owners.
Avg. unlock order is the mean position an achievement occupies in a player's run, measured across 688 randomly sampled owners — Steam publishes no such figure. It is shown only where at least 5 of them hold the achievement, which is why the rarest rows are blank: at 0.7% only a handful of sampled players have it. 98 of 101 clear that bar.
