What is the average daily DA variance, start to finish, at your local track?

350’ in central NC.

Depends on time of year. I’ve seen it in the 2,000 range of swing

Late May through early September 700 feet would be about the average looking back a few years in my records.

Rarely more than 300-500 ft. variance on the same day, but easily 2000+ from day to day is possible. We're on an active "front line", where things can and will change in a hurry.
