The precise numbers don't really matter - that is why a 'healthy' range is given.
Changes in readings are more relevant. In my case if I put on weight there is a noticeable increase in the numbers... whether that is 125 to 140 or 130 to 145 doesn't matter, that is time for me to react by popping Amlodine until I can reverse the increase,
Just take 10% off your readings and get on with enjoying your life.
