Breakdowns cluster at 7pm, with 616 of the 1628 recorded closures starting in that hour - so the ride you most want is safest earlier in the day, not saved for last. A further 1021 rides simply were not running at opening, which is a late start rather than a fault and is counted separately. A further 163 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 17 Jul, when 42.5% of the park's ride hours were lost and 69 of 69 rides went down at some point.
