[Wheel of Time] Were there any ages where the Dark One phoned it in?

So, while most things that the Father of Lies says are suspect, one that nobody has any issues with is that the battle against him was fought "countless" times.  It even makes sense given the cyclical nature of time.

But, given that he knows with certainty he gets to try again and again until he finally succeeds, does he really give %110 each and every time?  Are there any ages where he sees the dragon and thinks *.:This new Dragon seems mightier even than Lews Therin, I shall send a few darkfriends to ruin his day and then I shall go back to bed until the next age:.*?

Or does he go all in each and every time?

He has no reason to not give it his all. 

There is no price for failure, he doesn't lose power, he doesn't really have a physicality that is punished. Yeah, being imprisoned sucks, but it's not like torturous like it was for the Forsaken. Considering that vs what he gains when he wins, pretty worth trying as hard as he can.
