Injector offset vs battery voltage tables

I was going through my file and noticed that my injectors offset vs battery voltage table was different that what the manufacturer of my injectors recommended. I have the ID1300 so they provide injector characteristics plug and play data. The person that tuned my car before me used different data. My question is would there be any reason to change this data from what the manufacturer has recommended?

Not sure which platform you are tuning on, but some ECUs provide a default table data for compensations like that. Do you know if the tuner chose those values based on his findings on how your set up was responding?

Unfortunately I cannot get a hold of the tuner. I have P59 ecm. I dont believe there are any tables that adjust the actual inject offset vs voltage.
