Well, its clever, and will save a bit of time. The only doubt I have is whether it will actually make a significant difference to landing rates, in view of the times saved which vary between a mini 6 seconds to a good 21+? ATC would need to work out the actual increase in runway utilisation given an average improvement of, say, 10 seconds or less per landing over the LVP period, remembering that not all a/c or crews will be either briefed/able or equipped to use it to its maximium benefit.
I was involved in the set-up of the LGW RETs and sadly have never seen an analysis of any improvement in occupancy post installation.
I'm really not happy with the last sentence of P1 para 5. I think that should be crew selectable.
EDIT to say that should read LGW RETILS
