T110's Second Century of Civilised Comfort

The_Chieftain:   Let me try another route.   I give you a ball.  I tell you to throw that ball to hit something over there. Most folks will not weigh the ball, measure the distance to the target, assess the wind resistance on that type of surface, measure the crosswind, the rate of acceleration caused by gravity and then scientifically know with certainty what figures to calculate in their head to result in a known velocity and parabolic arc to hit that target.  If you think about it, all that calculation is rather difficult. They don't change their calculation method if ball weight in grams is three times the range to target in meters or use a third calculation method if it's only twice   Most of us, when told to simply throw the ball at something will simply throw the ball. And generally get it close if not on target.  Skill is still involved, but no conscious maths. Thus here.  You should get a feel for what is about the dividing line for any situation.  Better players will apply that feel better.
