Weight / Fat loss

Ok, my new scales have turned up (bought due to this thread!):

Height 188cm
Weight 82.5kg
Fat 19.2%
Bone 2.8kg
Water 60.3%
Muscle 41.8%

Now I have no idea what I should be aiming for but keeping roughly the same weight and halving the body fat seems to make sense.

(Me Julie is a lot less fat than me)

Am I missing something here?
Fat + water + muscle = 121.3% Good job you've only got 2.8kg of bone!

My stats:

Height 175cm
Weight 75kg
Fat 24.7%
Water 51.6% (10% being Guinness)
Muscle 37.2%
BMI 24.8

Hmm, my %'s add up to over 100 too....

My weight has changed very little in the last year and since I've been 'trying harder' but it has 'relocated'.
