If RC has "very similar" offset times, they should publish them so that can be verified. Other injector providers like Bosch, Accel and FI Clinic now do that.
Having the correct offsets makes a big difference in arriving at a successful tune particularly idle and part throttle. The calibration we use today is now 25 years old. I imagine there's been improvements made to injector design since that time. Seems like offsets may have changed since 1990.
If current GM replacement injectors are flowing 19# that's ~17.4% differential.
Sounds significant to me.
