Dave,
Bill was just as confused as I was about why they'd want to do that. But then again, he brought up the graph of a few of the ICP maps and kind of made a funny face about them, too.
Thomas,
I have often wondered that myself with the stock MFD map as most of the maps are that way. I have always just rescaled the A/D counts so that 100 MFD occurs at 1023 (or 1000 in your case). I'll ask Bill tomorrow (since I hate bringing up work-related stuff after or before work hours) what he thinks about it.
