race results - no DNF or DQ

Hello all -- my first race in a while - 3/4/5 45+.  In a bit of bad luck, I flatted my tire coming off the practice lap and into the grid.  I ran for a new tire (to my car, not the pit), and got it on just as the whistle blew for the start.  I was in last, last, last place.  I crept up and blew the rear.  I ran to the pit, left my bike and went for a another new tire in my car.  Of course, the race was blown too.  But I wanted some laps and got back in.  I stayed out of the way and finished the race.  I couldn't hear what the ref said at the end, but I crossed the finish.  

Question is -- I got no results.  No DQ, no DNF, nothing.  Just curious as to why.
