Been saying this for a while myself, but it is nice to nice to have confirmation.

One of the most overheard phrases in firearms training is the old adage of “slow is smooth and smooth is fast.” In my career as a trainer and shooter, I seem to recall it most often told to me by people who were slow and maybe smooth and honestly had little business telling me what actually was fast. Words have powerful meaning, and as an instructor, it is important for us to use the correct ones when trying to impart skills and knowledge to our students.
Let’s start by examining the root of the adage. It has been told to generations of shooters that “slow is smooth and smooth is fast.” Some trainers apparently got tired of uttering the entire phrase, which has its own flaws, and had skipped right to “slow is fast.” NO IT IS NOT. What relevance the full phrase had is erased by shortening it.
