Re: 'Relics': missed opportunity?
I figured Scotty was still kidding, stating some serious advice in a joking way. The advice being to always build an engineer's safety margin into time estimates just like you would build a safety margin into your usage numbers for a piece of equipment. It makes you look good when you beat your estimate, and keeps you from looking incompetent when you fail to meet one. I do this at work, and it is good advice!
As the brilliant philosopher once said... Everybody, have fun tonight. Everybody, Wang Chung tonight.
