World Cup Jabulani’s knuckleball

By Tangotiger, 07:28 AM

What is the optimum range of speed for a baseball knuckleball?

Analysis compiled by NASA’s Ames Investigation Centre experts, who specialise in the field of aerodynamics, revealed that the Jabulani becomes unpredictable at speeds in excess 44mph.

Further criticisms voiced by a host of World Cup players, before and during the tournament, of the ball’s inconsistent flight patterns have been attributed to it’s ultra light weight of just 440 grams which makes it vulnerable to a force known as the ‘knuckle effect’.

NASA also believe that the effects of altitude could have increased the unpredictability of the ball with most stadiums in South Africa at least 1,000 metres above sea level.

Shades of the NBA introducing the new basketball that NBA players almost immediately denounced.

In corporate america, we follow a process: test, test, test.  Not just unit testing (testing in isolation), but also stage testing (testing in a production-level environment, meaning actual real-world environment).  It seems to me that alot of the sports testing includes the marketing department in its lifecycle.  Marketing should only show up after final testing.
