I only died 4 times

I beat F.E.A.R last night on normal difficulty and I only died 4 times. Once while throwing a grenade at a ninja that was too close to me, second because I fell off a ledge, third because I fell off another ledge, and last because I didn't kill the final boss I. Time before she grabbed me. Does this mean I'm a F.E.A.R pro? Haha I was just hearing this game is really hard
