The threshold for detection is half the axis range, would it jitter as much?
Some joysticks & their firmware versions send data in invalid format, I think the throttle in Warthog is one of them, sending data in big-endian format. But when we patched it, other Warthog owners complained that it broke for them. It looks like there are two versions, but we do not have enough info to discern them and work around it.
