Do I really have to explain this? Are you dumb or just a dick?
If the former, it is because it is a completely different scenario than getting an extra attacker at the end of the game, which success rate is based on scoring a goal under any circumstances. There is no detriment of being scored on because the result is losing, which you already were going to if you don't go all-in. And like I said in my post, which you clearly didn't read or are too dense to comprehend, the risk is worth taking when the alternative has such low odds.
Obviously if played throughout an entire game then being scored on with an empty net absolutely effects the end game result. Then the question at hand is completely altered, what is deemed a success and what a failure differs in the two scenarios and needs a different statistical approach, but I think anyone with half a brain knows that a team without a goalie is going to do worse over a 60 minute time span.
