Has anyone every used the program WinISD for calculating box sizes based off of all of the specifics on the actual sub speaker that you are using?

It told me that the "optimal" size for the 10" that I am getting is:
Width 17.126"
Height 26.575"
Depth 10.866"

But that is like 2.862 cubic feet; more than TWICE what the maximum recommended box volume from the manufacturer is. I was told that it was a really good program, but the data doesn't seem valid.
