I think the COMMANDED velocity will be quite instructive, but I'm not sure there is a hal signal that displays that.
But, you are running version 2.5.3, and I think that version may not obey the GUI velocity limits on G0 moves, which I clearly see in your screenshot. So, you might change those few G0's at the beginning of your G-code programs to G1 and see if that prevents the problem. If so, then you may need to turn down the MAX_VELOCITY in the [TRAJ] section of your .ini file. Or, possibly, the velocity is fine but the MAX_ACCELERATION value is too high.
