In the unlikely event anyone is interested in the Wed hypothesis:
The 75mins crying stopped when the first person entered and did not continue any longer.
She was second or fourth.
Why didn't Rachel hear this crying for 75 minutes on the WED being next door?

Reply 'Kate did, when we sat down at the table on the Thursday night, Kate said that erm, Madeleine and Sean had cried, said they'd been crying, erm and you know wondered where she was, or wondered where you know, Mummy and Daddy were, erm I mean this was kind of after Madeleine disappeared, we talked, she mentioned that when we sat at the table on Thursday and then after Madeleine had disappeared, erm McCANNS said, oh well I wonder whether on the Wednesday, you know somebody had tried to get in perhaps or had got in and they'd seen something, erm you know and I was next door in the apartment but I mean I didnt hear any, well you know, I didnt hear anything, I could well have been asleep, erm you could hear quite a lot through the apartments because Grace, she always wakes up early but because she seemed to have diarrhoea every night, she'd wake up sort of six o'clock most mornings and we'd always have to put her in the, in the shower or in the bath first thing, and Gerry and Kate would always hear that and so you know, most of the comments first thing in the morning would be like, oh so Grace was up early again, she'd be invariably screaming her head off, so'.
