Pathfinder Mythic; Extend Spell, Mythic Extend Spell, Channel Power.

[Barstro]

What is the final duration of a spell cast with Mythic Extend and Channel Power?

Channel Power; "You can also expend one use of mythic power when casting an arcane spell... If the spell has a duration greater than 1 round, the duration doubles."

Spell; Duration "T"
Extend - 2T
Mythic Extend - 3T

Is Mythic Extend with Channel Power 4T or 6T?

[Morcleon]

It would be 6T. In Pathfinder, the only thing that applies the "two doublings is a tripling" rule is modifiers to rolls:

When you are asked to apply more than one multiplier to a roll, the multipliers are not multiplied by one another. Instead, you combine them into a single multiplier, with each extra multiple adding 1 less than its value to the first multiple. For example, if you are asked to apply a ×2 multiplier twice, the result would be ×3, not ×4.

There's no information on how real-world values work, but D&D 3.5e has this extra part:

When applying multipliers to real-world values (such as weight or distance), normal rules of math apply instead.

In the absence of anything else to contradict both this and the fact that real world values multiply normally, it should apply them as normal multiplication, since time is a real-world value.

Actually, time is a relative value, so you have to multiply the whole thing by your family.
