Going back to the OT, my quick search through twitter indicates USAC National Sprint cars have had 8 different winners in 15 events ran so far. KTJ, Windom, Bacon Courtney, Stockon, Darland, (listed S. Cottle in error), and now Ballou.

OP is correct in that the 4 mentioned have an abundance of podiums; however, there’s still been 11 different drivers finish top 3 and that doesn’t include Grant or Coons jr (yet...)

Might not last but so far a new winner average of every two shows and a new podium finisher almost each race seems pretty diverse to me... and who on here would be surprised if Grant, Leary, Boespflug, TMez, or Coons, got a win to keep that average going? Not me.
