Im one trophy away from a MVC3 S rank, the last one I need is the 320 missions in the mission mode. So i when into mission mode to see how close i was and... I cant find how many missions I have done in total anywhere. I can see I have done 51.66% of the missions but no tallied up number. Am I missing something obvious or is it not there?

I'm in the same boat. 320 is the number of missions for all the characters, minus the four you unlocked. So you have to do all but 40.
