I'm not pitching for perfection on the crèche records. With a manual system of the type operated I would expect to see anomalies. I would be quite suspicious if the crèche records were 100% accurate, and tied in perfectly with every cross-reference, including the nannies, other parents, the activity records, the T9 statements, workers in the Tapas area, tennis instructors, sailing instructor and more.
Up until around 10pm on 3 May 2007, Madeleine was a person of very little consequence, at least to anyone outside the T9.
I, for one, would not expect to see anyone, bar perhaps 1 or 2 nannies, to be in a position to say definitively that Madeleine was at High Tea that day. It was just another holiday meal with a fairly big bunch of parents, kids and nannies. The T7 could have nailed this, but of course they were at the Paraíso.
Clearly, if Madeleine was dead by High Tea time, we have a conspiracy that involves Kate McCann, Gerry McCann, David Payne, almost certainly Cat Baker (but possibly A N Other on the 'substitute girl' approach) and potentially fiddled crèche records. Personally, even at this span, I would class this as a massive conspiracy, without going any farther back, when the conspiracy gets even bigger.
Hence, I would like to have a look about what we know about the crèche records for the afternoon of 3 May in particular, but keeping an open mind as to their accuracy at other times.
