The Shard stat tracking is on your save data when you go to load a game along with a bunch of other stats including stunts. For some reason it doesn't start telling you the overall shards total in game until near the very end of the 350 shards. Maybe the last 15 it showed me in game.
By pressing pause you can see what stunt your on next but I wish there was a list somewhere in game. I was too lazy to look it up online during my first playthrough and I ended up doing some of the harder ones like knocking 3 guys off a roof with 1 blast a very roundabout way. A another I was pretty much screwed on. It was the one where you have to blast back a grenade back and kill an enemy. It became way too tough to get with guys that randomly throw a grenade after just chilling for 10 minutes shooting at you!!!!! Woah thats a repressed memory there...
So you really need to have a grenade launcher enemy to attempt it on. Check out the stunt list first before you get to far and save yourself any aggravation.
