Good question, and perhaps a confusing answer. The win list is for all time, and the local circuit didn't always have different rules than URC. In fact, there was a time when the URC racers were ahead of the local Sprint Cars. There was also a brief time when URC allowed bigger motors than the local circuit. (Remember there were several years when Jack Gunn had a 312 limit on local sprints) The problem lies with when should URC count and when should it not count. The easiest solution is to count the wins. An explanation I once used when trying to explain this was that if you look at things before the World of Outlaws and All Stars were formed. Back then USAC(or AAA earlier) and URC were the traveling Sprint groups that visited the area. I'd compare USAC of that day to the WoO, and URC of that day to the All Stars. Hope this helps. To take away URC wins over all time would take wins away from most of the top local racers of all time. Consider that taking away URC wins would not just take wins from guys like Fred Rahmer, Lance Dewease and Kramer Williamson, but also from Kenny Weld, Jan Opperman, Ray Tilley, Gus Linder, D1ck Tobias, Keith Kauffman, Van May, Bobby Allen, Bobby Weaver, Kenny Slaybaugh, Frankie Kerr and Kenny Adams too.
Thank you for the explanation. IMO, the guys that stick out like a sore thumb on the all-time PA list are Curt Michael at 40 wins and Sean Michael with 38. I am not saying that to rip either of them as drivers, but 30+ wins in URC is a lot different than 30+ wins at any of the weekly 410 tracks.
