Nightwing managed to dodge blows from Green Arrow, and Batman is superior to Nightwing, so this should give the two feats.

According to this link, Green Arrow could dodge bullets. I'm assuming he goes at Supersonic speeds, or Mach 2.5.

Assuming the distance between Nightwing and Green Arrow was 1 metre, and the human reaction time is 0.25 seconds, will give us that Green Arrow's speed in Nightwing's perception of time is 4 m/s.

850.725/4 = 212.68125

Therefore Nightwing and Batman are 212.68125 times swifter than Green Arrow, or Mach 531.703125.
