I can immediately think of three reasons not to.
- It's easier to replace a Victor if you don't have to recalibrate afterwards.
- Sometimes the joystick value isn't directly coupled to the motor output (i.e., one-stick control, or a holonomic drivebase).
- Autonomous control is seriously impaired if the Victors aren't consistent.
The only compelling reason I see for calibrating a Victor to a specific joystick is if your program is simply copying the input value to the output. For a basic robot under complete manual control, that is perfectly appropriate. As soon as the program gets at all fancy, however, it becomes important to separate the input calibrations from the output calibrations.
