4th job Single Target DPS

I have tried entering my exact stats and equips for my Evan in to this chart but I can't seem to get the same range if I am using a weapon with Magic: X% potential. I'm like about 1500 above my actual range. If I use an item without Magic: X% potential, I am like 20 off which isn't too important, probably caused by rounding somewhere.

I'm not sure if this might be the cause (tried messing around with this to no success) but, could it be that the "% Attack" in the Equips sheet being used an extra time? When I change this value, it changes the "Total Attack (Equips)" and "% Attack" of the Stats sheet.
