Please let us not confuse the meaning of 'stroke'. While it does have meaning in the diving world, it does not only apply here. 'Stroke' can you apply to any individual in just about anything as deemed fit by his/her peers, sometimes those peers don't even know the person.
As another example, still in the sporting area, I grew up in a bowling family..we all bowled, mother, father, and brother. Having bowled since I was 3, I have been around plenty of strokes as well as been one.
One particular example of a stroke in bowling, is the guy who pays $179.99 for a brand new ball that hooks like no other, buys the brand new shoes, all accessories, he even has a brand name shirt on (bowling related of course),...shows up for league play the first night...walks up there and throws a dead straight ball and barely picks off the 4, 7, and 8 pins..walks back and complains the lanes are too oily!! NOW THAT MY FRIENDS, IS A STROKE!!!
