It’s disappointing that the focus of this thread turned to being only about davening too quickly. The OP was also being critical of the other extreme.
Most people are prone to zoning out if they have to sit through tedious, yeshivish davening. Yet, most people also can’t truly say every word and still keep up at an MO, 5-minute p’sukei d’zimra style shul. The common-sense intermediate doesn’t seem to exist today in America when it comes to weekday davening.
