To spare others the same googling: 175f = 79.4c, 180f = 82.2c.
What you're doing is called cupping! I've seen it used mostly to set up tastings of multiple different coffees at once. Generally it's recommended to stir the crust at some point so that the grounds fall to the bottom of the cup. Also, you're brewing at a pretty low temp though. Even for dark roasts, I would consider brewing a touch hotter and see what you think.
Or Paragon even. That game was so fun back in the day before it got killed. If anyone can make something that fun again, it's probably Valve.
