Were?
Were what?

No blood on Nevills bed. None of the blood on the carpet belongs to Nevills blood group.
Clearly Neville was not bleeding very much at that time, other than a small stain on the wall at the bottom of the stairs and a couple of drops outside the bedroom, there is no particular trail of blood.
Likewise your scenario seems to lack a blood trail.
The pathologist(Vanezis) never gave the range of shots. It was Malcom Fletcher who came to his opinion by looking at photographs.
Yes it is Fletchers report, having seen Vanezis, Hayward & Elliots statements, x-rays, photographs, a pyjama top and nightdress and test firing the rifle at various ranges with and without moderator attached, noting discharge residues so produced.
The area on the floor plan only indicates where the shooter could have been standing.
Yes, the shooter was standing somewhere in the hatched area, they are not thought to have been stood outside of this area.
Really? Your scenario requires Nevill to be shot in some odd position and not bleed. With June getting out of bed and running away from the shooter while Nevill runs in the opposite direction towards the shooter. June and Neville cross paths then Nevil runs past the shooter in the door way and down the stairs.
Erm no it doesn't, if it is so preposterous why has it been accepted by the various experts and at trial, appeal, CCRC review etc.
The killer enters the bedroom, stands at the foot of the bed and starts shooting, shell casings are ejected to the right.
June is shot a number of times, she sits forward and collapses out of bed on her side.
Neville is shot a number of times but manages to run past the killer out of the room and down the stairs. The killer pursues and after a struggle in the kitchen Neville receives the 4 fatal shots.
The killer returns to the bedroom where June has managed to move around a little and shoots her an additional two times whilst standing in the doorway, the cases eject to the right.
Not a single convoluted ricochet in sight.
