I guess likea lot of things we all have our own definitions. Your comment is a description of what I call a partial passthrough. Granted the broadhead has done its part in as much tissue damage as possible but a partial passthrough does not allow me to inspect the arrow and learn more about the shot and how to go about on the recovery.

I agree it doesn't have to go 6" in the ground but a complete pass through definitely gives me more knowledge than a partial pass through.
