Adjusting our expectations by sin(45) got us much closer to what we actually saw in 2013, when we used the Vexpro Mecanum. In 2011 & 2010, when we used the Andymark Mecanum, the rollers were stiffer and we didn't see the same behavior. I'm only working from memory for 2011, but when we measured the speed of the robot it was close to what we expected for fixed wheels.
When we get far enough on our robot this year, I'll be sure to repeat the encoder position check. This year's robot may not be a good choice to use as a benchmark though, I'm pretty sure our weight will not be evenly distributed.
