I have been plyaing around with my new Index S2, after having the S1 for years (and using it daily). My body fat is between 8-9%, which has been confirmed with manual testing at a sports clinic a few times in the past years. The S1 was pretty much spot-on, giving me a pretty accurate reading.
The new S2 however is cosistently giving me a body fat of 19%, sometimes even 20%. This is completely off and proven to be wrong. How can the new scale - with supposedly better sensors and improved algos - be so dramatically off?
