Dodging Bullets

In theory any moving object can be avoided given the right time frame.  Now assuming we don't have super speed, what's the minimum distance needed to successfully dodge a bullet?  We're also going to assume we move the right way not the wrong way on reflex.
Here's the maths:
Average human reaction time is 0.19 of a second, for visual stimulus.  So yeah, with this theory you have to actually see the gun fire.
Activation of muscle fibre averages at 0.008333 of a second for humans, so the total reflex time is of 0.198333 of a second.  Let's round that up to a tidy 0.2 of a second.
The bullet speed of a 9mm pistol is 340m/s.  .2 of 340m gives a 68m minimum distance to dodge a 9mm pistol bullet.
Alternatively, given that distance and pistol accuracy, you may be better of just standing sideways, sucking in your gut and hoping for the best.
Now, here's the distances of some other firearms to try not to get shot with:
.22 pistol/rifle fires at 290m/s giving a 58m minimum dodge distance.
Magnum fires at 460m/s giving a 92m minimum dodge distance.
The average assault rifle fires at 920m/s giving a 184m minimum dodge distance.
Well there's the mathematics for the theory, good luck trying that out in the field.
