The list has been too quiet lately, so I thought I would post this for the group, but especially for Ed and Tracy.  The spreadsheet was created by Gary Casey, a Lancair driver, to calculate the fuel/cost penalty related to going fast vs. a little slower, and allows you to see the difference in fuel burn with specific headwinds and tailwinds.  Gary has graciously permitted me post it on the Fly Rotary list.  Since Tracy has stated on a number of occasions that he is a "thrifty" pilot, I thought he might enjoy plugging some numbers into the spreadsheet and seeing how much he is saving.  The formulas are based on a Mooney airframe, so keep that in mind.
