A lot the victim consideration comes from establishing an MO, which is tricky. Even the most experienced profilers disagree because the evidence at this stage, is sketchy and unreliable. There seems to be some consensus that the general MO was to manually, or mechanically, strangle the victim into unconsciousness, and then start with the neck and progress. That is why Elizabeth Stride remains a credible victim, as her wounds suggested mechanical strangulation with her own silk scarf before the neck wound was inflicted.
If you accept that as an MO, then certain things fit. But Martha Tabram is an issue still. There's little evidence of strangulation in this case. So it takes a leap to say she was a JTR victim. But did the MO evolve? Perhaps. The killer was definitely opportuntistic, so while there were certain things that remained more or less consistent, there were others that evolved, especially if you consider Mary Jane Kelly, and the fact she was murdered indoors.
I haven't seen the programme in question, but I must say that I have seen other cases in that series and they do not inspire confidence.
