The columns on the right represent how often the ride experiences a closure in the first hour the park is open.
Using Expedition Everest as an example:
- "Closed" means that on average, it's not running for about 7% of that hour.
- "None" is the percent of days when we've seen no downtime at all in that hour. 86% is pretty good.
- "10%" is the percent of days where the downtime exceeds 10% of the hour (i.e., 6 minutes) - 14% of days, or about 1 day per week.
- "25%" is the percent of days where the downtime exceeds 25% of the hour (i.e., 15 minutes) - 10% of days, or about 3 days a month.
- "50%" is the percent of days where the downtime exceeds 50% of the hour (i.e., 30 minutes) - 7% of days, or about 1 day every 2 weeks.
The "Full Day" column on the left is the same thing, but over the course of an entire day. Note that Test Track runs for an entire day without downtime ("none") around 20% of the time. So on 80% of days, there's at least one measurable downtime incident.
The blue line represents the average attraction in each park. Attractions above the line have worse reliability than average.
Data are from My Disney Experience since 2016, many millions of samples.
