Let's say I am lying on the ground when my friend runs over me on his speeder bike, does it feel like I've just been run over by a bike or as though a light breeze just passed over me? There doesn't seem to be much visible disturbance in the film, however, it's possible that's just a budget reason or that the compression of the ground simply isn't very visible.
Alternatively does this vary depending on
what that writer wants different models of repulsor lifts, the specifics of the planet their on, the altitude the repulsor lift is functioning at etc. etc.
Legends answers are perfectly acceptable if nothing is found in canon.
