PRACTICE NOTES Have no way of getting and have not seen ANY site that does 10-15 laps averages or showing what lap is the slowest. Sometimes the NASCAR Leaderboard Average speeds are posted here, if they are accurate or they are combined with NASCAR Media speeds to get as much info posted as possible. Example if a driver slows down considerably on a lap [wreck or debris on the track], the average laps gets messed up and may not be posted. What you see posted is the best that could be found, no need to email and ask for other practice stats.
