Weight Watchers - WW weight range question

Hi, I do South Beach but am wondering what the weight range is for a woman, 42 years old, 5'4" tall. I've seen various ranges and am wondering what WW recommends. Thanks and have a great day!

Here's the site:

Thanks! looks like my recommended weight for WW is higher than mine. I appreciate the help :)
