What do the LTFT boundries do? I did a search and it didn't yield much. The only thing I can find is in the help file which says something about the FTC cells "covering" the table. I under stand the breakdown for cells 0 through 15, but I don't understand how this effects anything. The PCM has trims for each of the smaller individual cells on the VE table, so why do the larger cells set by the LTFT boundries matter?
