I don't know if we ever saw data for the new Madone rim - just heard that it was downgraded to avoid making the disc bike look so bad...
Aside from Cannondale - discs haven't gone well for anyone. Especially Cervelo who went from a bike with standard bars to full integrated
But Cannondale shows it is possible. Or it could have been an aberrant test??
I think the new Aerohead is supposed to be faster than the old one, which would probably put it down around the SystemSix. Of course that bike has been plagued with issues that seem to be related to trying to get the weight down to something in the range of a rim brake bike.
My guess is that most of the recent gains are down to the more integrated cockpits. Old school bar and stem combo left a few watts on the table, so a real disc to rim brake frame aero comparison would make most disc bike look even worse
