Samples: runs of the stage reported in the time range. Loots: total number of the item dropped in those runs. Percentage = Loots ÷ Samples, the expected number dropped per run, which can exceed 100%. Sanity Required Per Item = Sanity ÷ Percentage. Time Range: since the drop table of the stage last changed.
