Max upwards stab (i.e. a/c nose down) angle: +4.2°

A stab angle of 0° corresponds to 4 units of nose-up (ANU) trim at the lever. Presumably the purpose of ANU units is simply to avoid confusion between positive and negative values, so it may well be that each ANU unit increment = 1°.
So, assuming the MAX is not terribly different, you may only be 2 operation cycles of the MCAS away from having your stabilizer at full stab-up (nose down) travel.
