treil - tanita scale measures bodyfat a COMPLETELY different way from calipers. Further, it has the ability to "measure" accurately, i.e. to 2 places right of the decimal, however there are so many additional variables that go into that measure that is becomes almost meaningless if you are trying to make even any relative comparisons -- your water composition can vary soo much from day to day, hour to hour even - if you are takign 2 different measures to get a delta of change, you'd have to be very careful about measureing under the same circumstances - e.g. right when you wake up w/ no additional water consumed yet, no am cardio, etc. The whole thing about "no way are you 25%" -- its irrelevant if you are tryign to compare to a caliper measure or what we in fitness normally refer to when we talk about competition bodyfat. It just isn't.
Sorry for the little rant - but its just not even worth talking about because that same response comes up & its absolutely not measureing anythign remotely comparable to caliper measures. Just want to be clear. Its not that its "inaccurate" - its just not a measure that can be looked at or compared to a caliper measure or really as a change in bodyfat comparison.
