I posted the very question in the WiFiFoFum and never got an answer, but it has to do with the way Dell Programmed the A12 ROM here's the I posted in the WiFiFoFum forum which was never answered by the developer. I had to answer my own question!...

As of right now you will not find anything as accurate as you want until Socket and wifi fofum come out with a patch dealing with the way Dell's WLAN and A12 ROM work.
Socket communications has been giving customers a run around for nearly a year and no patch yet.
This of course all deals with the A12 ROM and the X51v's. There is nothing out there that will give you the fine granular numbers (readings) you want. The best for now is Dell's own built in WLAN
