I think since 150 to 155 is the ideal temperature to extract sugars from most grains, they probably want you to heat it to 160 and let it sit, so the temperature drops into the range for the majority of the hour. It will probably start out at around 160 and drop down to the range they want you to mash at during the hour. This is of course just speculation, it would be helpful to know how much grain you are using, what kind of grains they are, and how long the directions say to boil it.
No matter how rich you are, you can still only drink 16 or 17 liters of beer a day.
