We missed some practice time at the beginning of first practice due to rain on Thursday night and some water problems on the track, but the teams still got a decent amount of time on the track. Qualifying will be held on Saturday afternoon (starting at 1:30 pm ET) and that will be the last time on-track action before the AAA 400 on Sunday. Just a side note: five of the last six winners at Dover started inside the top 5.

 Average Practice Speeds:

Average practice speeds are calculated by taking the average speed of each driver in each practice and multiplying it by the number of laps ran. When you do this for each practice and add the  totals together, and then divide by the total number of laps ran, you get an average of their practice speed, instead of just the one lap statistic you see when you look at practice sheets. I have found over the years that this is much more accurate as to whether or not someone has a car that is good for one lap or one that can consistently be fast. These numbers, however, can be skewed if a team puts new tires on frequently or rarely changes the tires.
