I did try resetting adaptations before, and the LTFT's remained the same, so the stored data isn't accessible thru the Foxwell, or so I believe. I'll try it again, but if resetting adaptations fails to set LTFT's back to zero, then I'll do the unplugging/replugging the MAF trick, to get back to zero.
