>By "cuff" you mean the brachial artery ones, right?
Yes, the one that goes on your bicep.
Anecodtally, it seems to be within the variance of the cuff (plus or minus 10).
Trying to measure both at the same time is tricky as you can't actually tell the Hilo device when to make a measurement. It does it on it's own scedule.
You are supposed to calibrate the bracelet against a cuff at least once a month.
