Breakdowns cluster at 7pm, with 328 of the 2,461 closures that started before the park's final hour beginning then - so the ride you most want is safest earlier in the day, not saved for last. A further 304 rides simply were not running at opening, which is a late start rather than a fault and is counted separately. The other 152 closures start in the 10pm hour, when the park is shutting - those are rides finishing their day, not failing, so they are left out here.

The worst day in this window was 24 Sept, when 92.4% of the park's ride hours were lost and 39 of 39 rides went down at some point.
