Eric,
The published coefficients were .1 for inline and .12 for transverse as I remember. So there is a little difference when the tires are 90 degrees to the direction of travel. So if a team were to design the assembly to drop for braking and was able to raise the inline assy so that the number of tires remained the same, the robot would have slightly better stopping. This comes at the sacrifice of steering though as the transverse wheels are not moving and contribute nothing to the steering stability.
