While this will not answer the question directly it will provide information to help draw a conclusion.
The ASMI used 27 college pitchers throwing at distances of 60', 120' and 180'.They also tested them from the mound 60.5'
The crow hop technique was used for all flat ground throws. At flat ground the stride was shorter with less external shoulder rotation. At 120 and 180' the trunk was more upright.
The post went to include concerns about arm issues.Just some additional food for thought.
