Breakdowns cluster at 7pm, with 41 of the 337 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 165 rides simply were not running at opening, which is a late start rather than a fault and is counted separately. The other 22 closures start in the 8pm 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 7 Oct, when 27.5% of the park's ride hours were lost and 10 of 13 rides went down at some point.
