All in all, there was a great deal of power to be found by matching the carb size to the engine's actual requirements rather than the equation. From the smallest to the largest, there was a full 45hp range in output-enough to really feel the difference or to win or lose a race. While bigger isn't always better, if you've got the motor enough to back it up, it usually is.
