Why am I 100.3% complete with the campaign?

I've played all the way through the campaign on Veteran, and I went back and got all the campaign achievements and located all the intel. However, on the main menu screen, the game tells me I'm 100.3% complete with the campaign.

Having a percentage higher than 100% is normal in things like the Multiplayer component, where it gives you a percentage based on how far along you are in the prestige track (so you have 100% at level 80, and then 200% at level 80 first prestige, 300% at level 80 second prestige, etc) but I don't understand why I have exactly this percentage for the single player.


I wondered this same thing for the longest time but I figured out the answer. You have 100.3% because on the level "Mind the Gap" there are 3 pieces of intel even though it only says there is 2. So since you found the 3rd one it counts it as .3% since it is not registered in the game. If you don't grab that one though you won't get the collect all 46 pieces of intel and you will only have 100%. It is just stupid that they put that 1 extra one in there without telling you it was on the level.
