We can't discount a non fatal wound to the neck first but things don't stack up with that as that type of wound wouldn't account for the spray as it would need to be arterial for that, it may account for the blood on foliage.
What I meant was that with three heavily bleeding wounds (the pathologist said the arm wounds would have been fatal "over time" ) there would have been less arterial spray when the fatal blow was inflicted because there was less blood circulating due to blood loss from the other injuries.
Also, I'm still not convinced that the spray was arterial - the positioning and amount of blood could equally be explained as having been deposited from Jodi's injured arm flailing.
That type of wound would have caused saturation on the clothing but items like the shoes one would think would have been contaminated with blood. Was she naked at that time? Well hard to tell but I would imagine that shock and her will would have meant that Jodi was trying to escape her attacker so was there any injuries to the soles of her feet? Or were her hands heavily blood stained?
There were no injuries to her feet, but clear evidence that she had been walking and/or crawling (I would say definitely crawling) without shoes. Her socks were dirt stained inside and out, suggesting they were replaced after having been initially removed. Her hands were filthy, absolutely caked with mud - it's possible - maybe even probable - that that "mud" was a mixture of Jodi's blood and dirt.
The shoes and socks were pretty much blood free, as were her feet.
It fries my brain trying to figure it out. If Jodi was stripped in one place before the knife wounds were inflicted, how did her clothing come to be found over the distance it did, and how did the bloodstaining get to be where it was (and not be where it wasn't, if you know what I mean?)
The only heavily bloodstained clothes were the t shirt and the hoodie, and we already know that some of the staining did not correspond with wounds inflicted. The bra was unbelievably free of blood, to have been found so close to the body. The underpants were bloodstained, but not heavily and there were "drips" of blood on the lower leg of the trousers.
I think, as you say, Jodi had to have been naked, or at the very least, semi-naked before the worst injures were inflicted - there is no other explanation for the lack of blood on the other clothing that I can think of.
I have always thought he damage to the trousers - the button on the waistband was "pulled through" the fabric, and the rips in the side seams were consistent with "pulling" - indicated that Jodi was either trying to run or crawl away from her attacker who was pulling her back by the waistband/upper area of her trousers. Bear in mind these were baggy trousers, so the attacker would have been able to gain purchase on the fabric around the hip area. Even if her upper half had been stripped by that point,either the face and neck injuries had not been inflicted by that stage, or Jodi did not get very far at all, otherwise, she would have been crawling through her own blood and the bloodstaining on the trousers is not consistent with that.
And, of course, this scenario still doesn't explain the blood staining on the hoodie and t-shirt.
