What do the numbers by “Global Unlock” mean?

Question

In my "Career" menu, I have some confusing numbers.

What's the "166"? I thought that was my experience, but my experience is -414, as denoted by the sad face.

Is it all the experience I've gained, ignoring the experience I've lost? Or is it something else? What's that number?

_{Curiously, after another game, my experience went up, and that 166 went down.}
