No, you're pulling numbers out of thin air. The action priority list for demo is about as useless as it is for Affliction.
Yes, without KJC, Demo would be a better spec to play on very high movement fights (Read: Vizier, Garalon, Lei Shi, Tsulong). That does not equate to "Demo would be the best spec for heroic raiding". Very, very few fights in this game can be considered "high movement", and that's nothing special about this tier.
