Hard to say, mostly because I'm sort of perpetually snake-bitten when it comes to die rolling. I've had major boss monsters completely fail to hit any of the players and come across as total pushovers. I've shot into melee combat and hit friends.
Probably the worst was on one of the few times I played Traveller and I completely blew the roll to land our free trader on a planet. The GM even game me a second chance on the roll and I botched that one. I ended up wrecking the ship and the GM had to end the session early because he had no contingency plans.
