Obviously the more granularity the better the data. The problem becomes getting data that you can be sure compares like to like. Total flight hours is the easiest to obtain and is not subject to different intreptations. Therefore I think the accident per 100,000 metric seems to be the most commonly used when broad comparisons are made
