Breakdowns cluster at 3pm, with 25 of the 204 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 64 rides simply were not running at opening, which is a late start rather than a fault and is counted separately. The other 14 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 26 Sept, when 19.4% of the park's ride hours were lost and 6 of 10 rides went down at some point.
