I think it's decided on your gear, are you overgeared for an encounter then you can slack a little with Penance and just use Fheals and shields. I find it easiest to keep Penance off CD to use it when the tank gets high burst damage or maybe someone else who might be dieing, depending if Weakened Soul is on my MT or not.
But in Ulduar it might be needed to keep Penance on CD since the tank would otherwise die.
