Body Fat% is a way off PART3

As the other thread "Body Fat% is a way off PART2" has been closed with another non-answer here is a new home for your observations and comments.

Personally I am happy with a difference of a few points from mechanism of measurement to another one, however I am not happy with a DEXA scan saying low 30s and an Index2 saying high teens.

So in my experience the Index2 doesn't do what it should at all.

    over time the scale does "get to know you" but look at those initial swings!  By the end the scale is more consistent but probably only about 3% points high.

    Weirdly my nutrition was incredibly consistent during the first part of this graph and less consistent on the second half due to holiday.

    My body fat is way of the chart also. I do a lot of calisthenics. And I do not input them in my Gamin watch (to much manual work). 

    I mostly use the Garmin watch for my cardio sports (not that much).

    Anyhow I am quite heavy for my length. (muscle mass). And if I do skinfold gauge checks. I should be arround 10-11%

    What does the Index S2 give me? 23.1%... That is actually the same result if I use some site on Google to convert BMI to Body fat (raw data).

    Did some chatting with Garmin but they were not helpfull at al to be honest. 

    I changed my activity profile from 6 to 8 (dont know how 6 got there in fhe first place (sport 7/7 1 hour a day at least) 

    But the fat % remained the same.

    That is a thing I will try this evening probably.

    Yes, the body fat is a way of part 3.

    I confirm that changing my sport level from 8 to 10 give me a slightly more accurate calculation. 

    Went from 23% tot 19%. Still not off for about 7-9%

    Change my age with 10 years however did not change a thing.

    Try with your fitness age and you'll notice the difference

    When I run (usually every other day) I weigh myself before and after. The after run weight is allways smaller then the pre run one and it appears that while running I am loosing body fat along with bone mass and muscle mass and I do gain some water.

    Beside that my fat percentage is at the limit between normal and overfat, sometimes going in overfat. I have 1m and 74 cm and the S size is almost too large for me.

    I did a lab measurement using BodyMetrix which estimates 15.9%. However, the scale is far from that, telling me 28% :/

    Not satisfiable at all...

    I must add that, sometimes, after a run the fat percent is greater than before the run. At least on one occasion it happened after a under 10k run so I have not eat or drink during the run.

    As you have lost water by sweat and the scale doesn't change your muscle percentage...then the BF% increases to give you a coherent value (not necessarily correct as we have seen)
