So I extracted my first aug and applied it to an armour piece, in this case it was a +4 speed mod for psychology. It got me thinking about aug stacking;

Could I extract 9 +4 speed augs and put one on every piece of my gear, giving +36 runspeed?
The follow up obvious question, can you have multiple damage augs for one skill, eg 9 x 50% damage giving an exponential amount of damage?

Thanks.
