I suspect 10ms will be a short enough time, but that depends on a few hardware specific circumstances (gyro float and accelerometer responsiveness come to mind). Your team's driving style may also play a role in customizing the algorithm. I am interested to see how this will turn out. Also, have you considered encoders on your drivetrain? I hazard a guess that 2 encoders and a gyro can produce a position close enough for your needs.
