Breakdowns cluster at 6pm, with 49 of the 247 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 193 rides simply were not running at opening, which is a late start rather than a fault and is counted separately. The other 2 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 19 Sept, when 19.6% of the park's ride hours were lost and 46 of 46 rides went down at some point.
