Mike:

Thanks for the input. I now am going to perform a physical test and see what the math produces with both the top up/windows up; and top down/windows up. I'm suspect there should be a difference between the two.

Also on additional checking of the number it appears there are two figures being reported, .45 and .42

I'll post my results after all the tests are completed.

Frank I
