Pick or Skip: Iron Club

Across 124 offers Iron Club has a 100.0% pick rate; the 124 runs that took it and 0 that left it are still below the sample floor, so no win rate is shown.

Taken 124 times out of 124 offers.

A win rate is only shown once that side clears the sample floor. Below it you get the run counts and nothing else — a 0% here would be a reporting artefact, not a result.

Pick rate when offered counts offers, not runs: out of every time the game put this in front of a player, how often it was taken. It is not the same number as the share of runs that end up containing it.

Pick lift is the sample-adjusted gap between runs that took the option and runs that passed on it. It is the fair way to rank choices, because raw win rates put the smallest samples on top.
