Do you have a cite for your assertion about Wilkins saying they chatted for 15 minutes please?
We spoke for a few minutes.
The conversation lasted for about three (3) to five (5) minutes.
The conversation lasted for approximately three to five minutes

Somewhere I have seen 15 minutes from Jez, but I am not wading thru pages of scriopt to find it.
Three to five minutes is plenty enough time for it to have haoppened.
For someone to have entered the apartment via the front door with a key, walked into the childrens bedroom , opened the window and shutters, picked up Madeleine, walked out closing the front door with the key takes me under 50 seconds and I am nearly 80 and mobility impaired.
Then passing Madeleine from the lifter to Tannerman over the walkway wall .... + him walking with Madeleine the short distance to Tannerman corner takes less than 30 seconds.
Total time from entering the apartment to Jane Tanner sighting = 1 min 20 seconds.
3 to 5 minutes is plenty enough time for it to have happened.
Measure out the distances and try it yourself
All this is my theory and included in that theory is the fact that i think it highly likely that the whole procedure was monitored and directed by an accomplice on the middle or upper balcony of block 6 immediately across the raod. He signalled with a pencil beam torch or flicking a lighter on and off IMO.
From the balcony viewpoint, he could see the area outside the front door and Madeleines window, to signal to any intruder there. He could also see the patio area and the bottom of the steps up to the patio window, to see family and friends arriving and leaving thru the patio door to check the children.
Additionally he could look straight into the sitting room and see anything going on
This is my mini theory (part of) ... and I am happy for anyone to constructively pull it apart ... if they can.
