Actually, percentages are beside the point. "Δ topspeed / Δ rank" just means: take the gain in speed you get by maxing top speed and divide it by the associated increase in rank fat. The greater the ratio, the higher the efficiency.

So you see, there ain't no such thing as "stellar rank percentages".
