Not wanting to start a war here.
As an OEM rep, just had to put that legal stuff in.
I agree, multiple load centers should be stated on Capacity charts when other than non standard forks are employed.
When the manufacture is notified, in written form, from a dealer of fork lengths that are unusual, meaning over 48", a capacity chart will be issued for that unit.
Never should an ooperator exceed the capacity or design of equipment.
Employ the proper equipment to perform the required task,
However my point was it should never be the position of an instructor to even hint that an operator can calculate or derated capacities other than stated on load charts, etc.

As instructors we have a responsibility to our students and employers to teach teh fundamentials and principals of safe operation.
