1/2 percent error rate, and using a lens with a relatively slow maximum aperture - and a lot of shots likely in less-than-ideal conditions? Yes, very impressive!

Also 80% chance of the shot being within 1/3 stop of correct exposure - excellent as well, considering all the different situations you were likely in during a wedding, and if I'm reading it right everything was based on auto/matrix (no exposure comp at time of capture).
