That is one point on which several beta teams are confused. It really depends on whether the references carry state information (best I can tell, some do and some don't). There have been a lot of ideas thrown around on how to improve things, both through examples and added documentation.

It is the rate at which the driver station sends data. That should be raised soon. I have not seen any recommendations as to a maximum.

There are 4 PWM type VI Libraries, a raw PWM, a Victor, a Jaguar, and a servo. The Victor, Jaguar, and Servo have different types of deadband and scaling control. You can use the raw PWM, if you want to implement your own methods for scaling and or deadband elimination.

For example, The deadband control for Victor is a boolean value, whether to scale the inputs to eliminate the victor deadzone and center on 127 (rather then 132) or not.
