Who's going to sit there and figure out that a 180 lb man standing (?) on
the end of a 24" breaker bar will deliver 90 ft/lbs of torque? What if you
needed only 75 ft/lbs?

Evidently you don't know math very well. There are books on the subject and
they give many formulas to work with. You will get that 90# much closer
than you state.
