Explanation: The calculator sums all systolic and diastolic readings separately, then divides each by the number of valid readings.
Details: Averaging multiple readings provides a more accurate picture than single measurements, as BP naturally fluctuates throughout the day.
Tips:
Q1: How many readings should I take?
A: Clinical guidelines typically recommend 2-3 readings, 1-2 minutes apart, averaged.
Q2: What's considered a normal BP average?

Q3: Should I discard any readings?
A: Only discard readings if there was clear measurement error. Natural variability should be included.
Q4: When is the best time to measure BP?
A: Morning before medication and evening before dinner are common times for home monitoring.
Q5: How often should I calculate my BP average?
