Do counters get stale?

[FireOfExile]

Okay, so I guess this question applies to more than just Marth, but I usually play as Marth rather than others who can counter so I'm asking here.

Do counters weaken as they are used repeatedly?

I do know that Shulk's does degrade with repeated use (like less of an active window I believe), but I'm not sure about Marth or any of the other characters with counters.

We'll have to count on Shaya, Emblem Lord, or someone else completely to get the data for you. But I'll go out on a limb and say it probably does.

Theoretically, I would imagine it being the same in Brawl.

I understand the modifier for damage is the same, but maybe the knockback?
