Actions are absolutely repeatable to a level of precision enough to achieve a desired goal. Hence your ability to type this comment, for musicians to perform music, for athletes to win games, so on and so forth. Repeatable actions are at the center of humanities ability to function.
All actions have variance, but the level of accuracy is only relevant to the prescribed goal. In the example of a basketball, the ball only needs to enter the top of the hoop from a given range of angles, at a range of speeds. As long as you are within this tolerance you will achieve the goal of making a basket. The whole concept of the game relies on this repeatability.
When a person learns to write they must draw a series of shapes. At first the letters are often difficult to read and will make the words they attempt to write unintelligible. As they practice, they refine their motor skills to within a tolerance of legibility. Each letter doesn’t have to be truly identical. Just within the tolerance of the goal.
So the key points here are; tolerance of repeatability is defined by the goal, repeatable actions are ingrained in nearly everything we do, and finally if you think that repeating your position through a series of pedantic semantics, goal post shifting or false premises is going to change the outcome of this argument, that might just be the definition of insanity.









In 2003 I worked for a small company that was attempting to be an early ebook publisher, before the days of ereaders and smartphones. It was too ahead of its time and closed after our first two publications. One of the books was on an old mining town, and part of my job was doing research and collecting photos and reference materials for the book.
I had the chance to read the diary of a miner from the 1860s. Keeping a diary was one popular hobby, but one thing that stood out to me was how he described a day off he had, it was a Sunday I believe and he spent 6 hours watching a bird and writing down all that it did.
What I gathered is that in the absence of entertainment or chores, humans will find things to fill the void. What seems extremely boring to you or me was very fulfilling to those with no other options.
