Given my demoing experience, I'd say women in the upper weight ranges can use the men's chart, but move up 1 weight category (down in ski length). The reason I say this is that given a man and a women at the same weight, the woman will have less power and muscle mass, thus will be less able to flex that length. In addition, a woman's generally smaller BSL will have less leverage over that length as well.
Otherwise, the chart seems to be an OK way to figure out an appropriate length range. I always buy a twin/pow ski in a length 10 cm longer than my main carvers but the manufacturer makes a difference. I mostly ski Volkls, so I can just blindly add that 10 cm when buying other Volkls. However, they measure their skis differently, so if I was to buy a twin from a different manufacturer, that might change.
As stroller says, different skis need to be skied in different lengths. That gives me a quiver with lengths from 155 cm (SL) through 168 cm (carver) and 177 cm (pow and twins) to 180 cm (GS). Really............demoing is the only way to truly know.
