No idea, sorry!
I know that the list is now solidly populated with "[W]" for the younger aircraft. However, the order of the list is now actually slightly arbitrary because total hours are no longer reported at the same date each year, so the list order could be comparing hours figures that are a year or so apart from each other (accounting for something like 3,500 hours per aircraft at current rates). And the list is only populated with reliably-reported or public domain information, and only periodically. So the fact that there are no gaps at the bottom end could merely be artefact.
One of the things it'll be interesting to see is whether G-CIVO was fitted with wifi during the recent work. As it happens, she's the "next youngest" in the list, but that's not necessarily significant.
