I mentioned in that item a table prepared some time back by Andy Coggan, which was similar to his power profiling table (which lists typical power to body mass of riders - W/kg for various time ), except it showed Functional Threshold Power (FTP) relative to aerodynamic drag (CdA) - W/m^2, instead of as per the original power profiling table.
The top end of the table would represent what's required to set a World Best Hour record.
In this way, a rider's power to aero drag ratio can be compared against the world's best.
Andy has kindly sent me the data, so here is the table for reference. Thanks Andy.
