Your quote is irrelavant.
The quote is completely relevant, because it treats turbo lag as a characteristic of the system. Which includes the motor, piping, etc and is based on actual output vs. your metric which isn't really realistic. Which is pretty much the only relevant metric, because a turbo doesn't have lag, it has an inertia and frictional losses. The same turbo in two different applications, will have different lag.
