I don't really see anything to attribute more weight to a BA CE passenger than a BA ET passenger; casual observations of people, bags and luggage carousels admittedly.
That leaves the seat weight. Well the modern seats come in at around 9 or 10kg each. So taking 50% of that for the marginal extra weight for a CE passenger on flights with middle seats free; gets us to +5kg … maybe a tad more for heavier crockery!
Anyway, applying that extra to somewhere in the order of 60kg to 120kg for the average passenger/baggage combo is pretty marginal. I'm happy to allow Prospero his 1.0x
