The "print on mat" column is totally bogus fabricated nonsense. Just look at the bathmat print. It's not possible to get "millimetre precision" from it. Also, by choosing where to place endpoints you can get any measurements you fancy.
ETA:
Big toe width on the bathmat is much closer to 2 cm and definitely not 3 cm. Both shape and size of it matches Guede and doesn't match Raffaele.
Yes, it's somewhat important to explain this whole bathmat print measurement issue properly. I realise that SA is rather proud of his little Excel spreadsheet which he would like to think is a "devastating" piece of proof that the print is Sollecito's and definitely not Guede's. This spreadsheet compares the Rinaldi measurements of the bathmat print with the relevant measurements form the reference prints of Sollecito and Guede.
But here is why the measurement analysis is utterly bogus and misleading. The main reason why it's so wrong is that Rinaldi conducted his measurement exercise in a totally biased, inappropriate and unscientific way. His own testimony confirms that he made an initial decision that the bathmat print more closely matched Sollecito than Guede - owing to his mistaken interpretation of the big toe impression on the bathmat print. And having made the (incorrect) decision up-front that the print was likely Sollecito's, Rinaldi then placed Sollecito's reference print and the bathmat print side by side and conducted his "comparative measurements" - and lo and behold it just so happens that various of the measurements matched with the now-mythical "millimetre accuracy"! It should go without saying that Rinaldi should have attempted to take the various measurements of the bathmat print without reference to either one of the reference prints (in fact, he should really have measured the bathmat print before even seeing the reference prints).
And that leads onto the second point that shows how bogus the "bathmat-print-match-to-Sollecito-and-elimination-from-Guede" issue is: the bathmat print is actually impossible to measure with any reasonable degree of accuracy. And it is certainly not able to be compared for measurement against reference prints. This is because the reference prints were made by the subjects having the soles of their feet evenly coated in a special printer's ink, then placing a clean, heavy footfall onto a smooth, hard, flat surface. In the case of the bathmat print, however, the surface onto which the print was deposited was hightly-tufted cotton pile, which also had a textured pattern making the tufts bend and give in varying amounts. And it's impossible to know the weight of the footfall onto the mat, or the spread of the dilute blod/water mix on the sole of the foot that made the print.
For all these reasons, it's impossible to get accurate measurements of the bathmat print, let alone ones that can be used for comparison to reference prints. Rinaldi - by his own admission - used grossly improper and suspect-centric methods to "match" the print to Sollecito's reference print, and it's highly likely that his measurement of the bathmat print was heavily influenced by his knowledge of the comparative measurements on Sollecito's reference print.
I imagine that Sollecito's defence team will address all this tomorrow. Essentially, Rinaldi's footprint analysis is bogus pseudoscience at its core, and in addition it was also carried out in a wholly inappropriate and improper manner. Sollecito's defence should easily have the ammunition and argument to thoroughly discredit this piece of "evidence".
On a more general note, I am thoroughly heartened by the lack of substance in both the prosecution and Pacelli/Maresca arguments. It seems to me that they have come
nowhere near proving that Knox or Sollecito participated in Meredith's murder. They all seem to have concentrated instead on varying degrees of character assassination, usually of Knox. Oh, and the "defensive wound" thing is nonsense too: if Meredith was submissive to a knife-wielding Guede right up until the end when she was on her knees, one would not expect to see either defensive wounds or restraint marks/wounds. Again, the defence teams will easily be able to explain this to the court.
Tomorrow and Thursday will be very good days for Knox and Sollecito, you can be sure of that. I believe that by the end of the week, everyone - judges, popular jurors and media alike - will be in no doubt of two things: there is insufficient evidence of the guilt of Knox or Sollecito, and it's very unlikely that they even had anything to do with the murder. Knox and Sollecito will be acquitted next week.
