It really looks to me as if you have a 203mm rotor on the front. That does a lot to keep things cooler! I've never had to stop to let my brakes cool either. But I do what you are describing also.
FWIW the more serious descents on the CT occur when you get into the San Juans. A lot of people run hydros on that route and never get into trouble. And there are those that do- hence the two bike shops actually near/on the route offer conversion from hydro to cable operated. I don't doubt that part of that has to do with how people are actually operating the brakes as you say.
My driver boiled the brake fluid in my Chevy Blazer years ago when attending a hang gliding fly-in at Silverton. She was descending the mining road on K2 which overlooks the town- its pretty gnarly. Should have made more use of 1st gear... When I released the bleeders on the calipers they actually hissed!
Not on the CT but a serious descent on the east side nevertheless.

I also know how to descend in a car and use the engine extensively. I would probably have warned a newbie to use low 4 and first gear.

Being she was a local and claiming she'd been on the road before, I wrongly assumed she knew what she was doing. The truck was already in 4 low but does you little good if you don't put the transmission to work! So much for assumptions...
