Hi Frank,
You are correct about the split wedge for focusing. The laser matte or precision focusing screen actually is accurate enough to allow manual focusing on any part of the screen.
I often focus and then reframe, and just adjust focus a little manually if required. Works well for me. This is exactly how I (often) worked in the analog days, except that initial focus is done by AF rather than by split wedge. And in my Pentax MX I always had a very fine matte installed anyway, and just focused anywhwere on the screen. It is not so much what works, but what you prefer. As long as one follows correct procedure, it doesn't really matter too much what is used for focusing, as long as it is possible to see correct focus or a good representation of it through the view finder.
HTH, kind regards, Wim
