Eric, you've questioned several times how NASCAR measures track length and I've responded that oval tracks used to be measured 15 feet in from the outside retaining wall, but with the advent of SAFER Barriers, I didn't know what they were doing.
Looking at info for tonight's Richmond race, the Richmond newspaper track facts chart showed the RIR track length being measured 13 1/2 feet in from the SAFER Barrier and remaining outside retaining wall.
When I plugged "13 1/2 feet NASCAR track measurement" into a Google search, I was directed to this question and answer at the JAYSKI site:
How does NASCAR measure the length of a race track?
NASCAR measures its race tracks with SAFER at a point 13 1/2 feet inside the outside wall.
Without SAFER NASCAR used to measure its race tracks at a point 15 feet inside the outside wall.
I am glad to see that my memory of the "old" standard of 15 feet in from the outside wall that I have repeated here on this site many, many times was indeed correct.
