Just wanted to chime in and thank you for all your (sometimes daring) hard work. It's really helped me out a lot. I'd not have the confidence, nor the know-how to 'twiddle' without this forum...
Last night, I tried out your method for tuning the 2103 processor for sharpness, and the new approach to SYSM=3 image processing; and all I can say is: "wow".
When viewing the Title.13, Ch.2 slide in DVE for tuning sharpness, the shifts in clarity on my set weren't so cut and dried as your article made it seem it would be. Mine's not a superfinepitch, so maybe that's the difference? There were some PPHA positions where the black/white vertical lines just blurred completely into gray (definitely *not* a "sweet spot"); but the one's that looked ok seem to comprise a *range* of 3-4 steps, vs. the obvious good/bad appearence between adjacent steps that your article suggests. I just set it to the middle of a good range, and it seems to be pretty good.
Also, what was troubling about going through this exercise was that the the box in the DVE pattern that includes the finest *horizontal* lines was not static on my display. It has a lot of flicker. Is there a way to make *horizontal* image refinement in the SM as well? This flicker reduces quite a bit when I set the TV to 'progressive' vs. 'interlaced' but it doesn't completely dissapear.
