Bleeding under pressure, that is with the heart beating will continue until the remaing total blood volume id between 40-50%, it's not pricise, but best to use the higher end to get a longest time.
The average human is said to have just under 5 litres of blood, women slightly less( although in pregnancy female blood volume increases significantly)
So the heart will start to fail when the total blood loss is between approximately 2 litres and 2.5 litres.
We can't use the flow from one victim to compare to another victim. There are too many variables, the most important probably being the actual wounds.
The difference between the two attacks, McKenzie and Nichols, is very important here.
Nichols has all the blood vessels in the neck, carotid arteries and Jugular veins completely severeved. The jugulars will cease to have a supply in seconds.
The carotids will each lose approx 370 ml per a minutes. That's 740 ml a minute in total. There is a slight drop in rate as the bleeding continues.
From this we can see that just from blood loss from the neck wounds, the heart is likely to fail between 3 minutes and 4 minutes .
