2, 3 and 4 are pretty common, in your average life altercation.
a lot of times it starts at 1 or 2 and then moves into 3 and 4 pretty quickly. when talking about your average real life altercation. sport i think is different as you start the fight from across a room basically and get to work for position with forwarned knowledge that you are indeed fighting.
in self defense, you often have to maneuver out of those positions if you favor something else. or be comfortable working inside
For whoso comes amongst many shall one day find that no one man is by so far the mightiest of all.
