How does Game Report define Blunders, Mistakes, and Inaccuracies?

Where at a point (thanks to databases and ever increasing data sets) than a computer can estimate your chance of winning based on the first move you take. Or rather according to the dataset, what your chances of winning are etc.
Blows my mind.

This will let you know what they look for
Title says it all. In this game a piece hung, or 400+ centipawn loss, was only a mistake, but in other games, I've seen less defined as a blunder. It also seems like even if you're down a lot, if you stumble into a forced mate, the game report defines it as a blunder.
