Max autobrake setting can jolt a lot of people off their seatbacks and create unnecessary mental stress; I wouldn't recommend that setting unless other deceleration devices were inop and you were on a very short pavement.
I have no B73 info, but the B74 at 3000psi sustained brake application would come to a full stop in 3,800'
In all my years of flying, I have never used "Max" setting, except in the sim.
