I'm not sure I understand your concern about guesswork. Knowing fuel injector duty cycle and fuel pressure gives you dependable consistent data. If you're doing DIY work and want absolute numbers then you need to calibrate your measurements, though you can probably get accurate numbers without calibration if you factor in your fuel injector's specifications.
