1. 'Maziness' and 'window' are useful concepts to
   illustrate (to our clients) the notions of
   reliability and unbiasedness when time-dependency
   is subject of study.
2. Study design, measurement quality, intervention
   strategy and validity of sampling procedures are
   the recurrent key issues in every study,
   data-analysis comes later on.
3. Is content reliability a strong enough concept
   to serve as a supervising criterion in strategies
   that warrant studies of high quality? Is it
   evaluable? Quantifiable? Unprejudiced?
4. The peer review should assess the design quality
   of the study as laid down in the study protocol
   before the study sets off, not afterwards if the
   results are offered for publication. It's too
   late then.
