If the cert is redone each time the tag expires, they usually don't look at it quite so hard as they would if the tag has been dead for 10 years or it's not there. Sportsman tag will go to 8.50. SFI 25.x will go to 7.50. That's a funny car cage and some more bars in the floor. Also weight is part of it at that point.

Like a competition license. It's easier to keep it up than let it go and have to get it all over.
