I disagree. Picture below shows racquet’s handle orientations relative to forearm axis with wrist in maximum ulnar deviation arrangement.
For pistol grip minimum β = 0° and with hammer grip β = 30°.
One can rotate wrist in opposite direction, clockwise, around 90° to maximum radial deviation. Thus maximum values could be: 1. Pistol grip β = 90°, 2. Hummer grip β = 120°.
