Amplify Elixir extract + Extend Potion discovery = ?

[thepuregamer]

Like the subject says, what do you get when you use amplify potion extract and extend potion discovery together? 4x duration? Not much is said about stacking so I am unsure.

Usually when you double stuff and doulbe stuff again it goes to x3.

This doubles the ORIGINAL duration each time.

So Mage armor duration 4 hours doubles the first time to 8 hours and the second time doubles the 4 hour part and makes it 12 hours.

This was stated back in D&D and while I have not seen anything speaking about it in Pathfinder USUALLY when no change is made use the old rules.
