People don't travel on averages, overalls, nor do they spread their working day out to the quieter trains - hence the rush hour.
And if a three carriage train is full off-peak, a six carriage train is full peak (and indeed a three carriage train full to bursting peak), then no, a maximum of five carriages turning up at a platform doesn't tell you that.
People do adjust their travel habits to make their journeys more comfortable. A wedged-out 3 car train at 1710 will see some people choose to catch a 6 car at 1720, for example, even if it is marginally less convenient time-wise. In the new world, if 5 car trains depart at 1705, 1720 and 1735, then the load will spread better between them. Furthermore, if the 5-car 1705 becomes overly stuffed, some will gravitate to the 5-car 1720 (or even 1650 if it suits them) if there is usually more room.
