Always experimenting, but for me effort is not a question. Toyed around with that for a while without much good result.
The best I can tell is we are always trying something, doing something. ("task")
Effort and Intent.
I have had success with just monitoring feel. Literally- "Feel". Or executing specific, pre-rehearsed swings. (feels)
Or just generalized thoughts like "Just manage."
Then there are concepts like Clear Keys. "Automatic Action." To manage neg thoughts, anxiety, tension. "Stay loose." A "defocus" of sorts.
With swing keys it varies. Start off loose. Lct. Usually monitor whatever is driving the swing. ("locomotive") And path. This part varies for me. "Swings are more like gardens than buildings."
Still not sure about target focus. Seeing if I/how I can fit it in. Best I can tell though is we basically know where we want to hit it. Is it necessary to "grind" on that more? We align clubface, body, pick appropriate club, etc. I have had success with specific focus at times though, so I don't know.
Target focus vs. visualization/imaging? I don't know yet. There is a lot to think about, if you do think about it. Different yardages (exact and not so exact), conditions affecting yardage, shots with degrees of curvature, etc. A lot of it is a guess whether you make your decisions based more on feel or logic. But preparation helps.
For now I don't do specific routines of movements. "3 practice strokes every time", etc.
Lots of stuff depends on the person too of course.
Even with your initial post Leo. "Step up and...do w/e" or "try hard, swing hard". Opinions are opinions and anyone can give themself about any command they want, but I'd imagine people have different tendencies with this. Your "Blueprint".
