Graft isn't affected by weapon scaling at all. Best way to replicate this bug is to use Graft with three different weapons, preferably Tomes. It seems to do the same amount regardless of your weapon or lackthereof mainhand or offhand -- it appears to be only counting certain factors. In my Elf's case, this might be the 40 LIGHT attack, the double healing base, and perhaps the offhand Stave FAI boost -- though this isn't very likely since it does the same amount even when my stave is mainhand anyway. Very weird. It also doesn't seem to be adding the weapon's actual flat power either.
