Should you include division by coefficient of variation in WV reconstruction for its normed 1D signal?
There is no benefit of dividing the new improved signal by the covariance of the original ECG and its improved signal like the following code; by the two decimal accuracy in Corrgrams and other more precise tools (eigen cor)

% Covariance http://dsp.stackexchange.com/q/35291/5633
% https://en.wikipedia.org/wiki/Coefficient_of_variation
utp = utp / sum( cov(u,utp) )'; 


Fig. 1 Left-hand-side figure without division by covariance and Right-hand-side figure with division by covariance - about marginal dependence and independence of the cases



Other inspected methods where I see no difference


Eigen cor matirx of the two
-M^{-1} about conditional independence and dependence


Please, let me know how to get more decimal digits in R corrgram panel.cor; I am trying to replace the problem by Didzis' p-value corrgram discussed there but having problems with finding the upper bound for the amount of points to maintain significant p-value.
