Why is MAP weighted toward diastolic?

Because the heart spends roughly two-thirds of each cardiac cycle in diastole, MAP weights the diastolic reading more heavily than systolic.

Mean Arterial Pressure Calculator

Mean Arterial Pressure (MAP) estimates the average pressure in the arteries during one cardiac cycle, weighted toward diastolic since the heart spends more time in that phase.
