Best times to check
Every opening our scanner has recorded for this permit (7,601 of them) by day of week and time of day (Pacific time). An opening is a date that went from closed to open. Dates closing are not counted here, and they make up most of what an availability change is. Darker cells mean more openings landed in that window.

Four Pass Loop drop report questions
How often does Four Pass Loop availability actually move?
Our scanner has recorded 118 availability changes for Four Pass Loop since it started tracking, broken down by month above. A change is any shift in the open-date set, so it counts dates closing as well as dates opening. Openings are counted separately, and on a different basis: 7,601 moments where at least one date went from closed to open. That is what the grid above plots, and it is why the two numbers do not add up to each other.
