Breakdowns cluster at 4pm, with 28 of the 76 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 124 rides simply were not running at opening, which is a late start rather than a fault and is counted separately. The other 1 closures start in the 6pm 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 29 Aug, when 52.2% of the park's ride hours were lost and 39 of 39 rides went down at some point.
