I found a website that had an extensive list of injectors and some data, I will find it and forward it to you (could be you have stumbled upon it). I will ask those that I know (as well as make a post on the HPT forum), of how it works and relay that info to the enthusiasts. I agree about playing with numbers, I much prefer to understand their function then mearly adjusting them.
Good luck with your schooling.

This "phenomena" can be seen easily with a set of Mototron 60s. When pulse widths get down below about 1.5ms, the injectors will struggle to open and the AFR will start to jump around. Get down close to 1ms and the injectors won't even open at all.

At that point you need to tell the PCM to add in x amount of extra time when opening the injector to have them deliver the proper amount of fuel.
