Stamper, I think to say that I'm not a 'fan of ETTR' is misstating things. I'm not an ETTR zealot. I recognise that ETTR has benefits but also limitations. Both are outlined in the text.
As far as your expectation that I would have talked about adding/subtracting EV from a meter reading to get a proper rendering of a certain area of a scene (typically a shadow area), that thinking isn't relevant with digital as it was with film. Particularly for one who employs ETTR. In point of fact, the 'traditional' Zone System methodology of placing the important shadow detail can work in conflict with ETTR depending on the drange of the scene and where that shadow is placed. It isn't relevant because, unlike with film where you only had control of highlights in development, with digital we have control of the entire brightness range which is why ETTR works. We can expose right, capture more light, improve SNR and then adjust the RAW capture to pull those shadows back to where we want them.
