Breakdowns cluster at 3pm, with 80 of the 471 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 325 rides simply were not running at opening, which is a late start rather than a fault and is counted separately. The other 65 closures start in the 5pm 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 1 Oct, when 26.8% of the park's ride hours were lost and 33 of 33 rides went down at some point.
