It seems to me that no matter which rate of profit one uses,
there is a subjective guess involved. That is, both the
ARR and the RRI require an estimate of how long, say, a machine
will last. Further, no matter which you use you've got to
guess what the returns will be in each of the estimated
number of periods.
