I think it's on page 13 of the manual there's a little picture to explain, but: The gain slope is set from the threshold point, so given an fixed IDC end point, say 80% for arguments sake, the earlier the threshold, the more gain at the end, because you a changing the slope of the injection curve, but from the threshold point, where it is always 1:1.

Make sense? If not I can draw a picture.
