My gears are too short, so I accelerate at 60-70% load to increase the pulse length and decrease the frequency of pulses. On hills, I accelerate slightly up them, into neutral down the hills (my car's terminal velocity on the steepest grades I've encountered in the Bay Area is about 50mph). I try to stay below 60mph because my engine's peak efficiency at 100% load is at 3200rpm (about 60mph). No vacuum gauge or load gauge, just butt dyno.

If the road is flat and there is a significant amount of traffic I don't pulse and glide, to be courteous to other drivers.

The last 1/3 of the Bay Bridge is a steep enough downhill grade so that the terminal velocity of my car is about 45mph, so I accelerate to 60mph and then engine off glide all the way down.

In the city I just stick it in 5th and let it roll at 20mph since I am too lazy to pulse and glide, and it wouldn't save that much fuel anyways.
