Breakdowns cluster at 5pm, with 220 of the 1509 recorded closures starting in that hour - so the ride you most want is safest earlier in the day, not saved for last. A further 279 rides simply were not running at opening, which is a late start rather than a fault and is counted separately. A further 52 closures start in the 10pm 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 27 Aug, when 29% of the park's ride hours were lost and 38 of 38 rides went down at some point.
