A Few Seconds Ahead is fine... in the context of the character sheet it's on, where Lore isn't her apex skill, and there are a few higher skills she could sometimes use instead. If you did try to make a character with, say, discipline & lore at +5... the power would just make your combats boring, because you'd always use the same defense. Even if you charged two or three refresh for the power, I still wouldn't want to allow it; it doesn't lead to interesting play.
I'd be much more inclined to make a short-range precog power that, say, granted +1 when you spend a fate point to invoke your precognition as an aspect (in addition to the fate point's normal +2 or reroll). Or maybe +2 but only for defensive uses. Something like that would be much more interesting - it wouldn't just invalidate large numbers of other skills, and you'd still need, say, enough athletics to get out of the way of whatever attack you saw coming.
