Inversion edit
Supposing that the Price Sensitivity Meter works as claimed and gives valid results, what is the rationale for inverting the price curves and interpreting the intersections? Is there a mathematical or conceptual argument for the inversion or is it simply a pragmatic? That is, inverting is done because it appears to work.Dischordate 23:27, 21 June 2007 (UTC)
Description of Technique to Critical Evaluation edit
Not sure if this is the right place to critically evaluate the PSM approach. It certainly merits criticism. The point of this article is to provide a public and open description of the technique - regardless of its merits or the claims of its proponents and detractors.--Zigmund Snorticus 16:49, 2 August 2007 (UTC)
Graphics please A graph showing example curves and intersections would be really helpful to the general reader. — Preceding unsigned comment added by 92.79.132.10 (talk) 10:07, 21 July 2011 (UTC)
