I would say that is a fair assessment. A track day might be worth 500 miles of average driving. Let's take your case, 14 track days, say that's equivalent to 7,000 miles plus the 6,800 makes 13,800 miles. Close enough to a nominal 15k. I'm not going to say that the 1 track day to 500 miles ratio always applies but it isn't unreasonable in my book.
