I don't agree with the philosophy of going harder on the downhills. As your speed increases, the power required to go faster increases exponentially. Mainly due to drag. To increase from 20 to 25 mph, there is something like a 75% increase in the energy required to achieve that additional 5 mph.

"At 20 mph, four-fifths of your total power is already spent overcoming air resistance. To go 25% faster, you need to increase your total power by 83%." --cycling mathmatics

It's just not worth it, I'd rather expend the energy when my bike is going slow. (Obviously this doesn't apply to short TTs)
