Yes, the math is easy and is what it is! The lesson and the premise - is that actual cost 2x your best guess and a profit factor of 50%, then there is the lessons learned from the past generation! As a young man, learning to turn handles in the garage with my old man and memories of better times as we worked on handguns (my dads hobby, my memories). There were plenty of other lessons learned over time, but a simple phrase of which has been with me for decades, and as expressed, works to this day. If he would have said to me at the time, multiply by 3 would I have remembered the lesson, I dont know. But the concept of doubling the best guess estamate and adding a factor was the lesson learned by a generation that went to the moon and back using slide rules. Something simple, something passed on and a respect to/of the past. |
