Found this in my shed yesterday....

Me either. I've always read the old 100 pounds = 1/10 of a second.
Edit: my math error,
Yes, 100 lbs loss of weight equals 1/10 of a second quicker, so 25 lbs loss of weight would be 1/40 of a second faster
The point I was trying to make was that my buddy would do anything just to go a little quicker
