Well, I'm happy for you that you found about this before the tournament on Sunday. Might come in handy :)
As for myself, I have never actually dodged a Blue Shell in Mario Kart 7 using a mushroom. I know it's possible, but the opportunity has never turned up. (Usually I just use it to go through grass/mud asap to leave room for another item.) I've dodged plenty using the boosters on the road though.
