Have a profile for myself (primary?) and one for my wife. Even though some of the readings are different enough to make it OBVIOUS who is on the scale, it seems the scale ONLY takes weight as the determining factor to assign a measurement to a profile (even this is not consistent). We are within 5 pounds of weight from each other and the scale consistently mis-assigns her readings to my profile (70-80% of the time). Our body fat measurements are significantly different (as are most men and women). Has anybody figured how to correct this.
It would be great if they could change the software to be more like the Withings program which, when the weight is within 5 pounds of the latest one (regardless of who weighed themselves last), asks you WHICH person is on the scale (you use your foot to answer) and assigns the mmeasurement that way (Withings software does NOT have as many secondary measurements as the Ultra so it has to ask).
