The quote from Huff is suppose to be: Most people will miss their GUESS by 15 minutes or more . . .
The operative word here is "guess." Mr. Spinnaker's numbers are a guess. I recommend this little book by Huff. It is only 142 pages long including cute illustrations. Little books are sometimes gems of condensed wisdom. Other examples: C. Northcote Parkinson, "Parkinson's Law and other studies in administration" Strunk & White, "The Elements of Style" J. Seward, "Outrageous Japanese" (for specialists only, where your specialty calls for knowing how to say "you're ugly, and your mom's belly button sticks out!" in Japanese.) - Jed
