\begin{quote)  \begin{quote}  \textit{But facts are chiels that winna ding  \\An downa be disputed}  \\-- from \textit{A Dream} by Robert Browning, 1786  \end{quote}  \begin{quote}  (But facts are fellows that will not be overturned,  \\And cannot be disputed)  \end{quote}  \end{quote}  Wave separation, wave intensity, the reservoir-wave concept, and the instantaneous wave-free ratio' (2015) N Westerhof, P Segers and BE Westerhof, Hypertension, DOI: 10.1161/HYPERTENSIONAHA.115.05567   This paper by three distinguished workers in the field of cardiovascular mechanics, concludes that both the reservoir pressure and instantaneous wave-free ratio are '... both physically incorrect, and should be abandoned'. These are very strong conclusions which, if they were opinions could only be debated. Reading the paper in detail, however, reveals that there it contains several factual errors in their discussion of these two entities. Since facts are different from opinions, I believe that it is essential that these errors be corrected before they gain credence by repetition.  \begin{quote}  \begin{quote}  False facts are highly injurious to the progress of science, for they often endure long; but false views, if supported by some evidence, do little harm, for every one takes a salutary pleasure in proving their falseness.  \\-- Charles Darwin  \end{quote}  \end{quote}  Because I am naturally prejudiced about the validity of both the reservoir pressure (Pr) and instantaneous wave-free ratio (iFR), having been involved in their genesis, I will try to present my arguments as transparently and fairly as possible. The format will be extended quotations from the paper (to avoid taking things out of context) with the relevant passage highlighted, followed by my commentary about the passage. The whole paper is available from the Hypertension web site and should be consulted directly if there are any questions about my treatment of the text.
