It can't be quantified.See that's the thing.... There's all this talk of real possibility of death... but what does that actually mean? A more lethal game...but what does that actually mean? I get the impression many want the illusion of these things as opposed to the reality... but don't want to state it outright.
The system, the play styles, is the DM hungry and in a bad mood, are the players eager to make new characters, the weather, were out of Mt.Dew....all of these things can have an affect on the "lethality" of the game no matter how you choose to define lethality.
The reality of these things is that its a game and there are (to paraphrase The Lazy DM) dials and levers that you can manipulate to make the game happen any way you want to.
At your table its your game and you play it how you want.
