Breakdowns cluster at 4pm, with 64 of the 117 recorded closures starting in that hour - so the ride you most want is safest earlier in the day, not saved for last. A further 80 rides simply were not running at opening, which is a late start rather than a fault and is counted separately. A further 3 closures start in the 7pm 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 29 Aug, when 52.2% of the park's ride hours were lost and 39 of 39 rides went down at some point.
