Here's the minute-by-minute results from that same tests. You can see how steady the lines representing each section of the fridge are. Those spikes are our regularly scheduled door openings --they never brought temperatures up by more than a few degrees, and the fridge was always able to pull them right back down. All in all, it's a fantastic result.
Here are the averages from the fridge's coldest setting. It's probably too cold, with most areas coming in below freezing, but note how consistent everything is. Also, note the freezer. We kept it at the default setting for both tests, and it yielded identical results after each. Dialing the fridge down didn't affect it one bit. Another fantastic result.
