Your comparison made me think even further about the similarities and I thought about USAC National Midgets and POWRi National Midgets compared to CART formula racing and INDYCAR/IRL formula racing. The obvious difference here was that CART and IRL didn't play nice together with regard to scheduling or rules. You couldn't race your formula car in both series, but you can run your "National" midget in USAC and POWRi.

I really hadn't looked at this prior to this thread, but Mr. Ray is right, several of the teams are running both series, and because USAC and POWRi are helping each other out with the scheduling, those teams are competitive in points in both. A quick study of the schedules reveals that of the 40 or so races each has on their respective schedules, only 6 overlap. That's pretty amazing! When I first looked at the Eldora field, I really expected the quick and easy answer to be "well, POWRi scheduled against the 4-Crown, so they siphoned off car count", but that wasn't the case at all.

So maybe that's a lesson that motorsports has learned. Play nice together. Share similar rules where you can be competitive in both series without having to run a complete second car/team. And then, maybe both sanctions can benefit from each other instead of beating each other up. AND, if teams want to run an aggressive schedule, they can run both series and be competitive for season points.
