The Price of Perfection
For all of those who seek ever lasting happiness, consider this:
If I swim, I swim 3km
Every 3 sec on average I take one arm stroke.
I need 150min = 2.5h for this distance in open water.
150min = 9000sec.
This means that I need 3000 strokes for this distance.
A single perfect stroke consists for me out of the right angle of entering your hand & arm in the water, to follow the line of your body with the hand with max. one dump distance and to extract your hand cleanly on the height of your hips from the water.
I have on average per swim session 5 perfect strokes.
This makes 5/3000 = 0.0016 = 0.16% of my total strokes.
I leave you the rest of the interpretation.
