YEs, great math skills anon….but lets use our biology skillz here.
When a mammal dies (heart stops pumping blood) you will not evacuate the whol body of blood. If a wound struck a larger artery or vein, then yes, you will get more blood. Smaller blood vessels will coagulate faster then larger ones especially with the lack of oxygen. That's why when you shoot dead body several mins old, the wounds wont bleed out.
I think the blood shown in the video is representative to the wounds sustained.
