L1011.
In flying the aeroplane for 27 years, I have found that it is nearly impossible to mis-load the aircraft, due to the unique design of the machine.
That rather large all-flying horizontal stab is the key.
Set 4 units nose up, and it works every time, heavy or light.
Having said this, at the present airline, last minute changes are handled with a new loadsheet...but the Flight Engineer, who does the deed, seems to complain quite a lot....
Having said this, we don't seem to have many last minute changes...the aeroplane is full all the time.
Surprise, surprise.
