Stack and Reach: Why It's Your Best Friends

Would any women of circa 5'6 care to share their stack and reach requirements? I'm trying to get a rough estimate for my wife, so she knows what size frame to look for broadly.

Or get a measuring tape out and actually measure her, plug the values into this calculator, and get some frame size options back:

I'm 5'4", one of my bikes is "medium", one is "small", one is "extra small", etc. I don't think I own any that are the same size as each other (though they all fit (mostly))
