You can, but not with the naked eye! You would have to log the data, so you can take into account the variations of flight, because the fact of the mater is the speed vary as you fly due to you making small altitude changes.. That is to say YOU ARE NOT CAPABLE OF MAINTAIN A PERFECT ALTITUDE !!! But don't feel bad most cant! Thus the variations in speed due to altitude changes are on the order of 30-40kph. So, the 11kph falls within that range, thus you can not desern which is which unless you also plot altitude

yes but these constant 11kph is the DIFFERENCE BETWEEN THE DB601 and DB605 engine!
