Six Day Gap at Dr Stefanoni's Magical Emporium
Well, the prosecution's answer to this is that there was a "Six Day Gap" between the testing of 36b and the most recent Kercher sample.
If you look here, you will understand the "Six Day Gap":

The thing is, though, the lab wasn't doing that much in those Six Days (7-12 November), and what it was doing . . . well, we don't know what it was doing.
One thing, though, is that the "Six Days" doesn't mean much when you look at individual pieces of equipment. For example, it seem to me likely that the Qubit Flourometer was not used during the Six Days (it appears that she was using the Real Time instead), and thus, for that piece of equipment, there is effectively no "Gap."
As to amplification, it appears that there were less than 50 samples run during the Six Day Gap, and only a few plates of electrophoresis.
So, I don't know that this "Gap" is any big deal. It would be better to have real controls to show no contamination, but I can't confirm that she actually ran any of those when she was quantifying via Qubit Flourometer.
I tried to slug through the page link (actually, I was on it before I saw your post, so at least I'm looking in the right place).
What I noticed from the page link, is that the lab apparently is regularly doing LCN DNA testing, with apparently no scientifically recognized methodology.
Also, there's apparently a significant amount of missing data, referred to as suppression. I don't believe it can all be explained as innocent. The 'cat profiles' from downstairs that return as 'human profiles', what's that about? Beyond that, the wide description of missing data on the page.
What gets me is the selectivity of missing data. Am I wrong, or does it seem things tend to go missing around the really important 'findings', for example, the five missing blood samples from downstairs (ID 600-604), we would expect those to be 'kercher', right?
ID 626 and 628, male semen profiles from rectal and vagina swabs are missing. (although 1 vaginal swab is positive for Guede).
The concentration of missing data around Raf's kitchen knife (ID 770 and 771), showing Kercher and Knox. An 89% suppression rate in this entire 2 day run (batch 2, Nov 13-14, 2007), is amazing, and this is where the extraordinarily helpful results are found.
The bra clasp wasn't found until 6 weeks later though, right?
It seems like a Jackson Pollock painting, where they have an abstract mess over a large canvas. Then by selectively showing what they want, and concealing what they don't want, they can create an impression of a 'finding'. As long as nobody looks too closely.
It's very hard to believe this process isn't intentional, and Stefanoni has a pretty good idea of what she'll be able to produce, if she looks at the right time, and properly frames her findings. It's too bad there aren't any 'polizia' for the 'polizia'.
Can I call them the PUH-LEEZIA?
So yes, they have answer, but it lacks plausibility when considered
osmotically with the balance of their deceptive practices.
