32 km/h is less 9 meter for second so you need teens of seconds to go out of weapons range so i don't think it's a lot
32km/h is a relative value, if you fly a P40C and be already at the edge or outside the gun range of the Ki-43-1, what is not too difficult with the poor guns, 32km/h less and you can get away. So 32km/h is only not alot, if you dont consider your life as important.
