I share your concern, it wouldn't be correct. This is what has held me back so far from changing my FD.

One of us around here should find time to put together a spreadsheet to display exactly how far off it will be. Perhaps in most cases, it might still come in a lot closer than the typical throttle bump from a heal/toe downshift anyway. I am not sure a few hundred RPM would make a noticeable difference.. but if there are scenarios where we are looking at 1200+ RPM off, it could become annoying or counter productive to leave SRM on.
