This article is a bit oversimplified, but I didn't want to talk too much in-depth about run estimators yet, and it's not as if people haven't already done it. I will go out there and simplify each of these run estimators eventually, but for the time being I thought it would nice to make sure everyone reading this stuff that's new to the scene that runs are the most important "currency" in the game. Feel free to drop by and comment however you'd like.
