To the gentleman who wrote the critical email about the term "balls out" within the article and thinks it is inappropriate by stating, "What place does gutter talk have here?"
FYI: It's a steam engine term, where the metal balls of the throttle operate under centrifugal force. When the balls are out, the machine is operating at 100%. In this case I was careful to explain within the article for those who may not be aware of that fact.
