Breakdowns cluster at 7pm, with 81 of the 557 recorded closures starting in that hour - so the ride you most want is safest earlier in the day, not saved for last. A further 309 rides simply were not running at opening, which is a late start rather than a fault and is counted separately. A further 40 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 21 Jul, when 72.3% of the park's ride hours were lost and 44 of 44 rides went down at some point.
