GhostRider62 has a stable of bikes, and his CdA on those bikes range widely. On one of those bikes, his CdA is around half of what you were assuming with that online calculator; he probably does have a bike where his CdA would be around what you were assuming, or even higher. That was the point of his post: he was refuting the claim that bikes don't matter. They clearly can. That wheelreason (and you) don't have such a bike doesn't mean they don't exist, so I classified wheelreason's post under #6. (Also, he's not 150 lbs; my guess is that he can hold that speed on that bike on around 3 w/kg, which isn't an uncommon power output at all.).
