These numbers are difficult to pick because the user can change a
multiplier using the buttons which changes the output range. However, many
programs use this range to perform operations of their own and the XInput
extension expects these to be constant for a given device. Hence, I've picked
values that are slightly higher than any reported by my test device in default
(no multiplier) mode. The documentation says the range is roughly +/- 400 but
I have seen numbers close to 1800 using the "sensitivity" setting as set below.
Some programs (GLUT) may get upset if the device reports a value greater than 
XInput reported it could.
