117  * the way up and down if there are multiple trip described in the

120  * @timestamp: first trip point crossed the way up
124  * @trip_stats: per trip point statistics, flexible array
138  * episodes and has to track which trip point has been crossed in
139  * order to handle correctly nested trip point mitigation episodes.
141  * We keep the history of the trip point crossed in an array and as we
