Just for a visual, these that I have numbers for are charted for the number of miles per injury and the number of round trips per injury (y-axis). x-axis means nothing, just spread out.



We are clustered around 400 to 750 round trips for each injury, and 7,000 to 13,500 miles per injury, with a couple of guys with much fewer injuries.

or this scatter-plot is easier to read, vertical is number of miles and horizontal is number of trips, for each accident of the given person:
