The ACPO guidelines take account for variations in peoples speedometers and the variation in the recording device. No Speed measurement device is 100 % accurate. Especially the hand held laser devices that can get readings of 11mph from a wall.
The 35mph reading on the gun is to be 100 % sure that the person was definately speeding. Officers who ignore this advice are doing it A) because they're an *** on a power trip or B) because they are chasing figures.
