In other words, you push on the pedal with 1lb or 10lb of force from your foot and it will translate that into 1.9lb or 19lb of force into the master cylinder - not taking into account the leverage from the pedal of course. Without the servo, about twice as much pressure on the pedal will be needed for the same braking force at the wheels, whether those wheels are fed with a single circuit, dual circuit, dual circuit with additional diagonal split in the event of one circuit failure to ensure both front brakes still operate, as for a system with a servo. This video gives a good (but Americanised) explanation of how the brake servo works. As you can see it doesn't even mention the master cylinder, single, dual or split braking circuits as they are a separate entity to the servo : https://youtu.be/wbTUvp-tD5M Only 2-3 minutes, it will help my words above make a lot more sense!
