The tightest mark 3 seating configuration is in the FGW refurbishment. I don't know off hand how many seats are in those vehicles and am too far away to go and check. They are too damned close together anyway, but you can work on those figures if you want to do the comparison.
But the easier way to do the comparison would be to work to furnishable length. Over the course of the life of the vehicles the seating is likely to be reconfigured anyway.
Continental 26m stock eg Corail appear to have 10 (first class) or 11 bays (standard class). It was not considered necessary to have large amounts of space at the ends. Using it for cycles and luggage is just an attempt to make the best of a bad job.
If those specifying the length of the vehicles had realised the potential problems, do you really think they would have made the same decision?
The FGW seats are too close together? Hardly. There is plenty of legroom unless you're a giant. The problem with that refurbishment is the height of the seat backs.
Sorry but you can't compare IEP coaches with continental stock, built to continental gauges, so not needing the slightly tucked-in coach end to fit in the UK loading gauge.
And you didn't make a wise choice of coach type for comparison. Where do you think the toilets on many Corail coaches are? At the coach ends, with the entrance doors inset. Remind you of anything, I don't know, perhaps the location of IEP toilets and entrance doors...?
Where else do you propose bikes should go? An IEP-arrangement for them is rather better use of available space than taking out seating space in the middle of a coach, as done on Class 166s.
There will also be luggage stacks inside the saloons in the same sort of locations as on Mk3s, Mk4s and Class 180s.
And if you've ever been on a Eurostar or TGV, you ought to be well aware that there are plenty of luggage spaces in the entrance vestibules, out of sight of seated passengers. Some TGVs also have them opposite toilets at the coach ends without doors. How could they do that? Ruining another of your theories about the unique horrors of the IEP...
