I got that from the FAQ section, on the Accel website.
It did seem high as most coils (with resistors) run much less. I just figured it was for their special need and who would know more about that product but the MFG??
It won't hurt to run it lower (using the value you said) to save the points, as it was running W/O any, which would be 14V.
The 'true test' here, would be to run it using their product line & see how long the points last. Then adjust the imput voltage if needed.
