Found this in my shed yesterday....

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
Nope. 25 is 1/4 of 100 not 40. .0025 or 2 1/2 tenths of a second.
