the fact that it takes place during an event doesn’t matter for this comparison as we’re trying to see how many of these people would have died if the event hadn’t taken place at all.
Then you must be ignoring information to show the truth that you want the data to show. Events need to abide by strict OH&S guidelines. If an injury or death occurs due to the negligence of the event planners, they need to be held accountable. This means that a death at an event should be compared to other events because day-to-day life isn’t governed by OH&S.
