How fast was the fastest mecaum?

[SpeedFreed]

For a summer project, we built an octanum drivetrain powered off of 4 CIMs and 4 Mini-CIMs, and geared the mecanum wheels to 20.5 FPS free-speed. We saw speeds of about 17 FPS, on the field, and 19 FPS in our school's hallways.

In addition, we used the OLD Vex 6" mecanum wheels (the ones that break), and still had them last well enough for whole off-season competition. We have since switched to the updated versions, and they look like they should be fine (haven't tested through a competition though).
