You can also just not swing as hard. Like if your normal full swing is 90% effort, you can take a little off by swinging 80% or 75%.
When I do hit less than full swings (not like partial wedge shots), I like to make a full backswing because my sequencing is better from the top, then I just don't swing as hard and finish short of my normal finish position (or even with a different look).
A small aspect is not zero. You can't just dismiss the mental aspect completely, especially when it comes down to being able to execute at one's highest level under pressure.

It clearly had an adverse effect on her. Maybe it cost 0.5 strokes which is a very small percentage of 80, but for someone trying to break a benchmark, it's just enough to be a factor.
I can hit a number of 3w shots: The high cut. High draw. Stinger. Low hook. Drop kick. Chunk. Top.
Just put a 3w in my hands and I can hit any one of these at a given time. Just watch the wheel spin around, who knows where it's going to land?
Are you saying you deliberately make decisions that are worse for your game for the sake of hitting those shots? Practicing is for practice time.
I don't need to hit driver on a short par 4 either, but when I do it's because I'm confident I can execute the shot I selected, not because I'm forcing myself to hit the harder shot.
You don't get enough repetitions during a round to really get quality practice out of it, so if you're not playing a practice round and hitting multiple balls, I'm not sure how this approach improves your game long-term.
So you flubbed a pitch shot over a bunker with your 60° wedge. What did you learn from it? Was it the club, your technique, the lie, etc.? Say next time you try your 50° and you flub that, too. What then? To me, it's just two shots. I don't read too much into that.
