New Stats - new scale

I just got myself a new scale today. My new stats:

Weight: 167 lbs
Body fat %: 17.4
Hydration %: 60

I was totally not expecting an increase of 2% in body fat and I was hoping to be at 170lbs because that is what the gym was measuring. I guess now that I have a scale, I can measure it during the morning right after getting up.

I'll try again tomorrow to see if measuring body fat during the afternoon changes when measured in the morning.
