I haven't seen much of today and nothing for about the first 2 hours so will review over the weekend as well as trying to catch up with the day's posts. However, in respect of what you say about Nel showing "there was a large area of splinter dispersement in the skin of Reeva's forearm" and Wolmarans' board only showing "a couple", I still don't see what was the actual point Nel was trying to make because, as I understand it, the mere fact there were splinters on at the site of the arm shot is what the Defence's challenge to the State's sequence of events covering the actual shooting is all about.
To explain. The fact there were splinters associated with the arm wound but none associated with the head wound when according to the State's proposed sequence of events both were hit at roughly the same distance from the door, imo raises serious doubts about the accuracy of the State's sequence placing Reeva down and over by the wall for both the head and arm shots, as common sense dictates, to me at least, that if shot at equal distance to the door both head and arm should have door splinters associated not just one.
OTOH, maybe I am interpreting you incorrectly, why would Wolmarans want to claim, as you say, that "splintering to her [Reeva's] forearm occurred further away", when it is precisely the defence's sequence that Reeva was much nearer the door when hit in the arm than the State maintains; a theory they support precisely by the presence of splinters in the arm wound in contrast to there being none in the head wound. A theory that imo does effectively deal with the contradiction that left the state's sequence wide open and up for challenge when Mangena failed to explain why the arm wound would have splinters associated while the head would did not if both were at a similar distance when hit. A contradiction that an intelligent and logical thinker like Masipa presumably is would find difficult to tally so compromising her reliance on the State's version in respect of the sequence of events for the shots at least.
And is such an apparently small detail important? Well, IMO absolutely yes, because as noted previously, the State's version goes towards proving the Bang...bang,bang,bang which in its turn goes towards showing intent, premeditation, knowledge of target, etc. while at the same time leaving time for the possibility of screams, all important for the State's case to succeed in it's maximum charge at least, while the defence's theory goes towards proving either a non existent or a much lesser gap between first and second shot, which in its turn goes towards showing spur of the moment, fear, panic, etc., along with a reasonable possibility there were no screams due to the speed at which the shots were fired.
