8 inch cup

10/06/2012 I made a hole in one on a par 4. It was a short par 4 about 235yds. I used a Pro V1 but is was an 8 inch cup, does this still count as a hole in one?? It was tournament and I did not buy drinks for every one. I have had two holes in one on par three's[4 inch cups] and the total cost for both was $300.00.
