Default Injector Selection and Tuning

I have been researching some info regarding the Accel injectors many of us use. In the calibration, there is a table that adjust injector opening times based on voltage. The lower the voltage the longer it takes the injector to reach full opening. This table compensates for that. This can contribute to what seems to be inconsistency in idle and driving quality especially with accessories on. Most people don't do anything w that table and so regardless if who manufactures the injector, the injector voltage bias is based on the stock Multecs. I am
looking for the voltage bias' of the Accel injectors to see IF they are different, by how much and what using them in the cal means in terms of driveability, economy and performance.
In the meantime, I ran across this vid by Jon at FIC demonstrating spray patterns for different injectors. Illuminating.
Not sure if it was posted here before but it's worth viewing
