i'd agree with this.

Currently i have a 2 mile section on my commute where i can p&g between 60-50mph by doing the following.
Use slope to accel car up to 60 in IDLE
Use dfco in 4th to engine brake to 50

Th slope is such that the car will often maintain above 50 for quite some time in dfco.

I also use dfco for slowing whilst driving in 'accordian' traffic
helps me keep my distance and keeps brakes avail if required in addition.
