How much does the length of a vacuum hose affect the vacuuming suction?

Virtually no effect on suction - may reduce flow somewhat. My central
vac pulls the same at the unit in the basement as it does on the
second floor about 15 feet up, using the same 25 foot hose.
Now before anyone says "of course, the length is the same" - no it's
not. There is an extra15 to 20 feet of "hardline" leading to the
upstairs.
