That is faulty logic - maybe the cascading solution needs to deal with
global quota and other aggregations that will rapidly break down your
scaling factor, or maybe there are few such problems can the cascade
part can scale way better than the underlying part. They are two
totally different scaling cases, so and suggestion that they are
anything other than an unknown multiplier is bogus.
