Chris Is Me is right, we did have some ratcheting issues, but these only showed up in the post season.
We ended up replacing all of the belts before Madtown. They all failed by the teeth falling off, a sign of under tensioning. Thankfully they failed in a graceful way (robot still drove, just slightly reduced performance) and it was moderately easy to replace the belts.
We are still figuring out what we will do next year. We are considering widening the belts if we have space, increasing pulley diameters if we have space, or just running with the same set up again because it lasted for 3 competitions.
