How can you tell when you've reached their limitations (flow),when the Injector Duty % reaches 100%?

 

I've been as high as 115-120% before I started leaning out and adding fuel in the map didn't improve the AFR

 

Is there any relation between the IPW/ms and IDC %? In the past I've always assumed 21ms was getting close to reaching the limitations of the injector. I've been researching but the only thing I've come up with is calculator..

Thank you, Chris.
