Steve said it was only throttle position and rpm and your diagrams support this.
Bosch pumps also had barometric compensating cells that would change the position of the stylus on the space cam, as well as a shut-off solenoid for overrun fuel saving, and a thermostatic compensator to change the amount of fuel delivered to a cold engine. Not to mention the '69 cold start solenoid.
