A lower first number will make the lever feel stiffer & require MORE pull by your fingers for any given brake effect. A bigger first number will make the lever feel softer, but will result in an increased brake effect for less pull by your fingers, but a longer lever travel.
Exactly, that's more pulling force as in you have to squeeze brakes harder for same braking force. You trade off lever-travel for squeezing-force. With more leverage ratio, you need less squeezing/lever-force with more travel. With less leverage-ratio, you need more squeeze/lever-force with less travel.

Yup, surface-area = (r^2)*Pi
