Any version has to account for the facts. My version is admittedly a theory, and does not account for all the facts because I don't know them all. Whereas many RDI so-called facts aren't facts at all, nevertheless RDI presents them AS FACTS. Thats the difference in credibility.
A good theory accounts for the known facts in a plausible way. RDI is no longer capable of this, because the plausibility of male DNA showing up innocently on more than one article of clothing that JBR put on hours before her death, AND showing up in crime-related areas (mixed with blood in her underwear matching with the DNA on her longjohns) is very, very low.
Setting the DNA aside, the plausibility that an adult who lives in the house, educated here in the United States, knows capital crime laws, would associate 1500 or so characters of their own personal handwriting with a capital crime also is very, very low.
RDI is also forced to choose between PR deliberately or accidentally misspelling 'advise' in her exemplars. Which is it? I believe that the plausibility that someone would smoothly write 'advise' in the RN and then smoothly write 'advize' in repeated exemplars, whether accidental or on purpose, is very, very low.
RDI has low plausiblity these days.
