Or just assume that your systolic will be about 3 points higher if you weren't sitting for five minutes, or whatever the normal correction is for you. You shouldn't accept a diagnosis of high blood pressure from your doctor if (as is most likely) they aren't measuring it correctly, but the deviation from the "correct" measurement also isn't random.
