I don't post much on PuristSPro anymore, partly because I haven't bonded with the redesigned site. But I certainly respect the knowledge of many of the contributors, and thought that some readers might find the article linked below, which I have recently published on a different (non-commercial) forum, to be of interest.
Cheers,
Tony C.
P.S. – If anyone is curious about why I haven't reproduced the material here, I can elaborate.
