Despite the issues mentioned above NHRA has had increased track attendance and increased TV ratings over the last several years.

National events have quotas for most if not all Sportsman cars. Some races fall short, other races fill up quickly.

Lots and lots of complicated issues here.

In my opinion the best way to watch a national event is the NHRA All Access product. It's not perfect but you hear the NHRA track announcers rather than some TV guy. My only issues are the product itself could be managed better and it takes a lot of time, just like if you were actually at the track.
