Mirari and extra turn spells

[Hesthesquid]

If I use {mirari} on a {time stretch} (for example) how does that resolve? Would I take 4 extra turns? What if I had {stronic resonator} on the field as well!? Would that give me opportunity to take 6 extra turns?

The total cost will be 16{U}{U}.

16{U}{U} is very reasonable for 6 extra turns...

Along with {nykthos, shrine to nyx} and {twincast} ,{candelabra of tawnos} and a few mana ramps... If my math is correct, 47{U}{U}{U}{U} will get you 24 extra turns...

That works out to roughly 2.15 mana per extra turn

I think that makes you win the game...
