Unfortunately we generally do not have markers on the trailing line to measure the true x and y velocities along the line. However, I would think that a reasonable first order approximation to the real velocities would be to measure the nominal tip velocity up to around MRF while the length of line from the rod tip to the fly remains constant.
How many markers do yo need? Try using examples where the fly is visible as a first approximation.
