Breakdowns cluster at 7pm, with 154 of the 950 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 424 rides simply were not running at opening, which is a late start rather than a fault and is counted separately. The other 31 closures start in the 9pm 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 18 Oct, when 74.7% of the park's ride hours were lost and 35 of 35 rides went down at some point.
