I've often wondered if DD trains really do help that much. Sure they may
move more people, but it also takes rather longer for the people to get
on and off. Is there any definitive evidence on this matter?

Not sure, but given that in a 26m UIC gauge coach you only get about
1.5 times the single-decker capacity due to space taken up by what
would be underfloor equipment, staircases and wider doors, if we were
stuck with 20m British-gauge coaches you'd get even less.
