I remember doing this in grade 8 as well, My car used records as wheels! So my actually took the same amount of time for one rotation of a CD with almost three times the distance to travel. We didn't have any fancy do-dad's on it back then and ours went all the way down the hall and hit the gym door!!!
That was a highlight of my life pretty much and it was two years before the robot team started at my highschool (that I wasn't a part of at the time)
Congrats on the win!! I love the waterjet, we don't even have that for our bot lol!
