hello, mostly posting to see if anyone knows how accurate the store bp machines are compared to the home ones. at the store i usually go to its usually 120-135/90-95. at home its pretty consistent with the systolic, sometimes lower. but the diastolic seems to be off by 10 points. i have an omron digital arm reader, suppost to be accurate. i just dont know what to believe. at home i usually get readings 112-125/78-86. not so much concerned with the systolic as that tends to fluctuate more with activity but curious about the 10 point differential between the store machines (ive tried out 3 others) and the bp machine i have at home. anyone else run into this or have ideas?
