I think the below text should be opposite?? At least mine throttle stick was below mid point and I moved to left (lower value) to get it to the middle. Please check and fix if I am right? If not then I understod something wrong?
Throttle tuning
The bottom two sliders allows you to tune the throttle control. Adjust the slider marked Throttle Hover until the copter hovers at the throttle stick’s middle position. If the copter hovers with the throttle stick above middle position, move the slider to the left by one tick-mark until it hovers at mid-stick, testing as you go. If the copter hovers with the throttle stick below middle position, move the slider to the right by single tick-mark increments until it does. Make sure to test each set of tuning settings as you go.
