I'm glad it helped.
I think it is possible the first couple of stabs were pokes. It might have taken her a couple of stabs to get use to the idea of stabbing someone. If that makes sense. OR, the pokes were administered during the scuffle. Like, she couldn't muster enough strength to stab during the hastiness of the struggle and/or was waving the knife around trying to make contact but couldn't tell if she was making contact. I think the slices probably came during the struggle, for the same reasons I just mentioned. I think this is probably when Travis incurred the defensive wounds.
If Travis was sitting in the shower when the attack started, I think it is reasonable to think the injuries to the right side of his body occurred first. The stab to his pec and the cuts to his right shoulder. Possibly even the stab to his neck/shoulder (the muscle where you rest your arms when hugging your man) and the injury at the base of his neck. I think it's possible she stabbed him in his pec and he reacted, trying to get out of the shower, and she continued with the stabs to the back. He may have been trying to crawl out of the shower, to stand up, and this is when she started stabbing him in the back. The injuries to the back were not deep and not life threatening. Picture it, he is on his hands and knees with his head facing towards Jodi. The stabs were to the upper portion of Travis' back, not his lower. His upper back was in closer proximity to Jodi. She may have been taking a few steps back as Travis was crawling, while she was inflicting the wounds. This may also be why the wounds were not very deep. Too much going on to, at the time, to be able to administer fatal wounds, so she gave several quick (motions) stabs. This may able have been when she inflicted the cuts to his head.
Travis was able to get on his knees, or stand up, and this is when the stab to the vena cava happened. And possibly the stab to the left quadrant. The front of his body would be vulnerable if he was on his knees and/or standing up. I think Travis may have been crawling to the sink in order to use it to be able to pull himself up. When he did, he coughed. IMO, he coughed once. The blood and spatter on the sink is not really that much in the whole scheme of things.
Another reason why I think he may have been on his knees is because of the location of the injuries. Jodi is shorter than Travis. If Travis was on his knees, he would be shorter than Jodi. If she administered the stab underhanded, it would be inline with Travis' torso.
I think it is plausible, when Travis pulled himself up at the sink, he started his run for it down the hall. Jodi grabs the gun, Travis runs out of gusto and falls to the ground, on his knees. Jodi shoots, it doesn't kill him, she cuts his throat.

I also think it is plausible the shot came first. From what I have seen/heard, there is some contradictions in how the shot could have/would have affected Travis abilities. From what I understand, the ME could not say for certain the shot was not inflicted first because of the decomp to Travis' brain. He could not pinpoint a trajectory because the brain started to liquify (it actually looks like it gets slimy and gooey). This is the reason the ME couldn't tell if there was any hemorrhaging, because of the state of decomp. I also think there was contradictions in whether or not it would have incapacitated Travis. The term incapacitating should be clarified, because it can be seen in different ways. Would it have incapacitated Travis to the point he couldn't move? He could have been incapacitated to the point he couldn't fight back effectively, so yes, that is incapacitation.
I've included the definition of incapacitate. I didn't use wiki because it was about imprisonment. That definition is still relevant to incapacitation, but I thought this definition was more appropriate in the use here.

I think if the shot came first, everything I have said previous followed in sequence, just add the shot first. Then, when Travis stood up at the sink, he started running, collapsed at the carpet and Jodi cut his throat at that time.
I wish I knew how to create a video thingy. It would be much easier to demonstrate than try to explain in type.
