I assume this doesn't include planes..

I believe it does, but I am not exactly sure if it includes vehicle-on-vehicle kills. I should have plotted with longer x-axis to see how far things extend, but already closed my notebooks ^^
If it does include planes, do you know how distance for kills by bombs are measured? If the distance between bomb and player is counted - instead of the distance between player and plane - that could explain the spike at <5(?) meters. That spike goes counter to what I would expect from my experience in game.

Including bomb/dart kills at all would probably do weird things to the stats, no matter how the distance is measured, as the plane is never in the same place when the bombs go off as it was when it dropped the bombs.

Things people said

And reading Youtube comments still gives me Turbo Cancer.

It really is quite frustrating when Helen Keller sets up her LMG in the only doorway in/out of an area.

What kind of question is that? Since when is cheese ever a bad idea?

Hardline is a fun and sometimes silly Cops and Robbers sorta thing and I think that's great. Or it would be if it didn't suck.

The kill distance is distance between killer (who gets +1 kill) and target (+1 death) at the moment of target dying, so in case of "delayed weapons" like bombs it can be somewhat off.

Seems like horse is the culprit of such high density at the lower end (surprisingly many of the kills seem to be with horse melee):

And it looks like dread shelling is responsible for the really long tail. It's getting meaningful numbers of its kills out past 500m.

Even with the bias of the horse, the aggregate bias moved the mean/media for tanks outwards. Those individual stats for the A7 and MarkIV show that the "typical" kill is at about 35, which is practically within AT gren range if the opposition reaches a bit.
