total = initial + mechanical + vacuum
They sell advjustable vac pods so you can limit the amount of advance the vacuum pod gives you, why you might wonder?
You have say 14 initial, plus the 20 mechanical by 2500, and you are cruising at part throttle so the vac unit adds another 10, now you have too much total timing and your motor is pinging at a light throttle cruise.
The slight improvement in gas milage at light throttle doesn't even begin to make up for the ugliness you impose on your motor with the vacuum pod and hose.
