The phrase 'Going 19 to the dozen' has been around for years, originating in the Cornish tin and copper mines back in the 18th century. These mines were often hit by floods, and relied on coal-powered, steam-driven pumps to clear the water. When working optimally, these pumps could clear 19 thousand gallons of water for every dozen bushels of coal hence, 19 to the dozen. The expression often means going at breakneck speed, but also became the benchmark for maximum productivity, in terms of both efficiency and effectiveness.
At Beyond19, we work with clients who want to raise the bar even further hence, going beyond the 19.
