NASCAR Stats Explained

Here are the NASCSAR stats explained that I use from time to time. The Drivers Ration has even more explanation and is located on it’s own page. The rest of the stats are explained right here. I may expand on a couple of the stats in the future. And there are some other stats that I will probably be adding here.

Thanks to Mike Ford over at NASCAR Media for originally helping me some further explanations of some items. Also, Mike is the one that put out the Drivers Ration Explained.
Here is the link to the Drivers Rating Explained.
