Breakdowns cluster at 12pm, with 116 of the 869 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 382 rides simply were not running at opening, which is a late start rather than a fault and is counted separately. The other 4 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 6 Sept, when 36.3% of the park's ride hours were lost and 40 of 40 rides went down at some point.
