This is only for the curious. I have seen the cycle just go back and forth regarding the worthiness of having something adjustable versus having something non-adjustable.

In my narrow experience, I have this to offer:

There appears to be a time-cycle in our trade. That a trend goes toward making things non-adjustable for a while, then leans toward making things adjustable. Then just changes again?

Is there any chance that this reflects on our abilities and competence previous to each cycle? Or perhaps reflect on the manufacturers?

How often do techs bypass non-adjustable things? How often do techs wish things were not adjustable?
