Now, since these series of articles have been written in 2017, it seems obvious to me that they were not incorporated in the original Delving Deeper boxed set, which was published in 2011 by Brave Halfling Publishing.
Or am i wrong? Were these considerations applied at the time when DD was release for the first time?
The site you linked to is my innocuous blog, which I infrequently post to. Those particular posts examining the Holmes combat example were, as you noted, written later than DD V1. About four years later, in fact
The short answer to your question is: "No". That kind of thinking hadn't been done (at least not by me) during the development of DD V1 (what's in the BHP boxed set). I don't think any version of DD to date attempts to cover combat at that level of detail. DD V5 (forthcoming) will likely have an appendix covering combat with miniatures (which is, in part, where this kind of thinking landed) but the main text will most likely retain a more abstract perspective.
FWIW, I'm not 100% sure your 2011 date for the boxed set is correct catacomb. Correct me if I'm wrong, but my recollection is that V1 first went out in PDF form in October 2012. Then John put out the BHP boxed set shortly after, in December 2012.
