  The abstract of "Contextual Values of Observables in Quantum Measurements" by
J. Dressel, S. Agarwal, and A. N. Jordan [Phys. Rev. Lett. 104 240401 (2010)]
(called DAJ below), states: "We introduce contextual values as a generalization
of the eigenvalues of an observable that takes into account both the system
observable and a general measurement procedure. This technique leads to a
natural definition of a general conditioned average that converges uniquely to
the quantum weak value in the minimal disturbance limit." A counterexample to
the claim of the last sentence was presented in Version 1. Subsequently Dressel
and Jordan placed in the arXiv the paper of the title (called DJ below) which
attempts to prove the claim of DAJ quoted above under stronger hypotheses than
given in DAJ, hypotheses which the counterexample does not satisfy. The present
work (Version 6) presents a new counterexample to this revised claim of DJ. A
brief introduction to "contextual values" is included. Also included is a
critical analysis of DJ.
