I am very glad you said this first, I was worried that if I posted that it would sound like I was being an apologist
for how my mod works with the Skyrim script lag. In fact I do believe it is more realistic for the resulting death to have some delay.
In the SCA we do not practice that, deaths are considered to be instantaneous except for “double deaths” were each person dies
because the two hit each other at “about” the same time. In that case the fight is redone until a clear victor comes of it.
However the immediate (first in the series of) results of the injuries we "would" inflict with our weapons (if they were actually sharp and we were not wearing full sets of
real armor) has been debated for many many years. And probably will be for a long time because we are not allowed to really kill or mame each other.
In this mod (eventually) I would like to prevent most automatic deaths and instead force bleed out animations. Then it would be up to you to
perform a coup de grace or leave them to their slow death. So perhaps this

game lag will work in my favor for once.
Anyhow I actually found the small script lag I was getting in my games to be somewhat realistic. I.e. if you hit a body with a sword it doesn't die instantly. It might even kill you too with its last breath. Then again, the lag was very manageable, usually less than 1 second, in my games.
