Because standards conformance tests always have maximum and minimum possible scores, we can divide the result by the maximum score and multiply by 100 to get a percentage. This allows us to easily average the results of each conformance test to come up with a composite grade.
Chrome lands in first place with a solid A. Firefox takes second place followed by Opera, both achieving a B. Standards conformance falls dramatically from there, with IE9 and Safari both earning Fs to finish in distant fourth and fifth places.
