As per the WH Edge 540 V-1 Manual they are posted in degrees.

HIGH RATE (3D) LOW RATE
Ailerons 23 deg. 16 deg.
Elevators 40+ deg. 12 deg.
Rudder 45 deg. 25 deg.

I used a Hitec programer and a Hitec servo throw meter and programed my servos. Then teeked the throw rates in my Transmitter
as I saw fit.
Hope this answers your questions
