I still feel finding out why Jez did not see or hear Jane (in fact anybody at all) pass by Gerry and himself while they were talking is crucial to understanding this case.
In earlier popsts on this thread, there have been several ideas why that could have happened, Rob. Have you dismissed them all?

Later Silvia criticises Jane's recollection. Which is all part of the same incident really. Being able to see who was carrying an unconscious child just moments after Gerry had been in the apartment and after he had switched on the lights to the kid's bedroom, and Gerry saw that Madeleine was OK.
We think that the child was unconscious but we dont know for sure !

Also the moments that you talk about could be minutes.
The Lifter: I am old and doddery these days but I reckon that if I received a signal to go in, I could have opened the front door, walked thru that apartment, chloroformed Madeleine, lifted her and walked out again in less than 40 seconds. That time includes handing Madeleine over the pathway wall to Tannerman then personally vanish.
Tannerman (with Madeleine): had a walk of no more than 27 metres, from the hand over place to Jane Tanner corner. At normal pace that would take about 20 seconds
So from entering 5a to Jane Tanner sighting would likely have taken less than one minute
Gerry and Jez chatted for about 3 minutes IIRC.https://www.quora.com/How-much-time-does-it-take-to-walk-300-meters-for-a-normal-adultSo it can't be Madeleine that child Jane saw. So why are Silvia and Jez trying to rubbish Jane's observation? A reconstruction is needed IMO and it is not too late.
Plenty of time as outlined above for Madeleine to have been lifted and seen by Jane T. They only needed 1 minute and there were approximately three available. So I think that Tannerman could well have been carrying Madeleine. Don't you ?Sylvia misunderstood Janes description IMO, but I suppose she could have had a reason to try and make Jane look a liar?
Jez could not see Tannerman at all, because Tannerman was totally out of his field of vision, being at roughly right angles to the direction that Jez was looking.
I think that there are three points there, Rob, that you need to re-assess.
