There's more then you think. Paragon isn't their only track. It's kind of a series that runs a hand ful of tracks. The had I believe 40+ cars race at least one race last year and I seen on their Facebook group page https://www.facebook.com/groups/244819046995505 that they have a few more drivers this year. Racing a schedule like Paragon has given them makes me think you could easily see 20-25+ steel block sprints each night.
