PWG...as far as accuracy...all the methods we can use ourselves at the moment are based upon assumptions, some of which may not be appropriate to us...such assumptions as age, weight...
Let me show you. I compare many BF testing methods to see how they work with my body. So here are the test results from the last batch...
16.34% -Tape measure 3 location
14.5% - Tape measure 2 location
9.4% - Skin Fold 3 Location
15.9% - Skin Fold 4 Location (actually an average of multiple tests of: 4 folds-15.1%, 1 fold-13.2%, 2 folds-19.4%)
11.27% - Skin Fold 7 Location
16.6% - Bio-electrical Impedance
So you see, they vary, but are mostly in the ballpark. I use the 4 Skinfold to track changes in my body because it gives the most available range for change (from 15.9 to 8% has lots of room) so I can measure smaller changes in my physique.
Your body fat tests at 8.99 - 12.5% using the Tape measure 2 location
That means you have 50.5 - 53 kg Lean Body Mass
and 5-7 kg of Body fat
You can do this too using the link I gave above for bodyfat testing...then you can monitor the changes in your muscle and fat as you buff up or cut down.
