No Tnight GP and this race was a special event at Hangtown. Replacment event? I don't know. It's whoever is in charge. I say full points race to end season. Screwed up year so be happy usac is still racing eh....
It's also always in our rule book on the USAC website, which shows how all the points are awarded.
Appearance points are used when the event's format deviates from the "standard" USAC format of single car qualifying, heat race, semi & feature.
The final two races this weekend at Merced will utilize the standard USAC format. However, they will both be "appearance points" races because they are a replacement for the Hangtown 100, which was to be an "appearance points" event all three nights. So, basically moving the "apperance points" races to another track in this case.
