Query: Is the proposed SI revision, according to the October 2018 BIPM
  documents, scientifically and formally satisfactory?   The use of the fundamental constants for the definition of the most important
measurement units of the International System, was considered a good solution
to found it on more solid bases. From further analysis, this solution was found
implying a number of consequences underevaluated by the BIPM until the proposal
presented for discussion in November 2018 to the CGPM, or at least never
clearly explained to the signatories Countries of the Metre Treaty. This lack
of clarity will affect the implementations of the revised System in the future.
Following previous illustrations, this v.5 of the paper is focusing on some
issues of direct impact on the correctness of the new definition and on its
implementation: how many digits, supported by the latest experimental values,
can be stipulated for the numerical values of the constants; why the present
experimental uncertainties do not support the pretended precision of the
constants; how inconsistencies affect some constant final database; why the
CODATA LSA analysis alone is insufficient to support the stipulated precision
of the constants; how the need should be explained of keeping the former base
units, in order to preserve their present magnitudes; which is the true
base-units/constants relationship; how the now-installed hierarchy between the
constants and the base units makes changes in the future metrological pyramid;
how to still use the present top national standards in future.
