Lemme , while I am impressed by your talents , playing home-made accident investigator can be dangerous for other people, especially when you appear " an expert" to the public and journalists that might take your version of events as established facts.
An example here on your beautiful graphs is you separate the aircraft transmissions from those of ATC , inducing to the non-professional the idea that the pilot was in distress requesting assistance ( vectores, vecrores Senorita.." ) and got no responses..
But even if you do include the ATC transmissions , they will be misleading unless you add that a controller can only give vectors if/when he/she actually sees the aircrfat position on radar. This was not the case , as she states she lost him ( whether due terrain or loss of electric on transponder still needs to be established )
Accident analysis it is a bit more complex that just taking You tube videos and Flight radar 24.
Finally ,as you said there are different VHF/ATC transcripts around, and the exact time stamps will be critical to establish the actual sequence of events.
Speculating of what might have happened is what we all do here, nothing wrong with that , but playing amateur incident investigator delivering home made " facts" is playing with fire. .
Before posting things , think of the effect this will have on the surviving people , the air traffic controller on duty and the families of the victims if you get it wrong.
