I can't see your ticker so I don't know your current weight, but that seems like a very aggressive burn rate. I have been using my GWF for about a week. I have my burn target set at 2500, so I can eat 1500 and have a deficit of 1000. I'm actually trying to zig-zag the deficit a bit, so I've been as low as about 700 calories and as high as almost 1400.
I've lost 3.6 lbs in the first 6 days, so I'm very happy with that, although I think the next couple of weeks will be the real indicator and determine how much I need to tweak.
I'd give it a couple of days to see what your normal routine is like - it gave me credit for WAY more than I really burn the first couple of days when I had programmed it but didn't wear it all day long, but now it's adjusted downward. I can get to 2500 with putting in some effort, going beyond that takes some real focus, so I knew I had to match my calories with what I could reasonably expect to burn.
