W/kg means little for near flat TT-ing, you need a high W/CdA for that and it's much easier to measure kg than it is CdA.
It's like BMI; it's a simple measure that is quite flawed and there are much better measures, but it's the easiest thing that people can measure with simple bits of equipment available in most homes (a tape measure and some scales).
