I see on google that a .050 lift gain from .006 to .050 lift would be a fast ramp rate. and .030 an avg ramp;slower]

or
An exapme of a fast ramp cam would be an Ultradyne Cam it had a 276int/276ex for advertised duration and the
duration @.050 was 221int/221ex. This is a fairly fast ramp for a
hydraulic lifter cam.
