Query: Diastolic okay, systolic not consisten

This is a convenient monitor, and seems to track well with a professional reading on the diastolic (lower) number, but is wildly inconsistent on the systolic (higher) reading.This is probably a limitation of using a wrist monitor, but with a 30 mm/Hg difference between what the monitor shows and what my doctor gets, it's pretty much useless for regular monitoring.Consider the Omron HEM-711 (upper-arm cuff, brachial sensor) or similar alternatives.
