Why Averages Matter More Than a Single Reading
Measuring and logging guide ยท Last reviewed November 2, 2026
A single blood pressure number is a snapshot. It can be shaped by the minute, the day, and the way it was taken. An average of many readings smooths out that noise.
What an average gives you
With many readings, one unusually high or low number has less influence on the result. That is why clinicians ask for a week of readings instead of one.
Average of readings, not average of averages
Home BP Log counts every usable reading once. It does not average each sitting first and then average those results, because that gives a single-reading sitting the same weight as a two-reading sitting.
Counts matter
An average of 24 readings carries more information than an average of 6. Every average in Home BP Log is shown with the number of readings behind it.
Averages hide nothing
Because averages can hide extremes, Home BP Log also reports the highest and lowest readings, and never removes outliers for you.
Interpretation is for your clinician
An average is arithmetic. What it means for you is a medical question for your clinician.
