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).
Power meters are a generic household commodity no?
(I meant it's easier, assuming you have a power meter, to work out W/kg than it is W/CdA like it's easier to work out BMI than it is to work out the far better measure of BVI.)
