Extra-Flexible Short Arms

Extra-Flexible Short Arms is a metatrait mention on page 5 of Shell-Tech.
It uses B53's Modifying Beings With One or Two Arms rules and combines the Extra Flexible Arms advantage with the Short Arms disadvantage, which have the same values and work out to a 0-point feature.
If you wanted to Afflict this however it would not be 0 cost. You would need to break it into its components:
*+50% to afflict a 5 point advantage
*+5% to afflict a 5 point disadvantage.
That makes it +55%.
That's one hole with 0-point features and why it is always useful to break down those metatraits into components.
