The OP is making it too complicated!
If you can get ten loaves of bread out of 7 pounds of flour you'll get
about for to five loaves from 3.5 pounds of flour etc. etc.
They probably give the half load (2500 watts) consumption just as an
example and also perhaps because the unit will be fairly economical at
that 50% loading.
If it use all its fuel in 10 hours on half load it might get anywhere
from 6 to 4 hours on full load???? It all depends.
It's a bit like saying a truck with a full tank of gas will go 1000
miles half loaded. And maybe 400 miles absolutely fully loaded!
Depending on the type of electrical loads plugged into the generator
it may or may not handle a full load; especially it it involves
anything with motors that stop and start such as fridges, freezers.
air conditioners water pumps etc.
Electric motors can have starting currents several times those of when
they running steadily or of something that has the same wattage but
operates without a motor.
So if the generator is running at say 75% (three quarters) of full
load and some motor cuts in as well, the generator could slow right,
trip out or even stall and stop. Rather like trying to drive car up
too steep a hill. And stalling the engine!
Experience will advise just what and how much can be plugged in and
used off the generator at one time!
If someone in the house has medical/life maintaining equipment to be
operated during a power outage one would not run the risk of the spare
beer fridge in the garage cutting in or someone plugging in an extra
coffee pot and shutting down the generator and killing the person. But
that's the kind of foolishness that can happen!
