Basic Action Super Heroes!

I am wondering how many Pages you can't use a Tiring power after you have used it Two Pages.

Is it that you can use the power again after a number of Pages that you used the Tiring Power...? (i.e. Super Speed is Tiring and you use it 2 Pages, you can't use it for 2 Pages, but then you can again.)

Or
Use the power two Pages, then only take ONE Page "off", then use it again immediately?

You can use a Tiring Power 2 out of every 3 pages.
