Our team crushed it at the JPL competition. At first we we're a little concerned the rings might end up touching the pipe, so we spend about half hour making slight adjustments and trouble shooting. Fortunately, everything worked out and our team had the fastest time of 2.26 seconds. The only way we could increase the speed would be by softening the impact so the pipe has less time to wobble. This might be done with more sponges or better cushioning. We can also might work on straightening the rings as much as we can.
The whole contest was a lot of fun and it was really interesting to see what designs other groups came up with. One thing I noticed is that all the designs using electronics or VEX parts either didn't work, or were very slow.
