I won't be doing it very often.

On the way home from work I took the back roads and had about a 6 mile stretch with no one behind me. I've been trying to get the Camry to glide. At first I couldn't do it, but I've become a bit more proficient lately.

First the good news - I don't have the NAV version so I just used the Camry's average mileage at the start and end of the run and interpolated. I started with about 20 miles on the tank and wound up with about 26. In that six mile stretch my mpg went from 43.2 to 48.9. Interpolating that would put my mileage for that stretch at over 60 mpg. And since I was not using the battery my SOC pretty much stayed near the max. So I didn't do it by depleting my SOC, causing the engine to stay on afterwards.

Now the bad news - It's very difficult. It will do it for about 3 - 10 seconds and then power will transfer causing you to make many adjustments. It's dangerous. Since the ICE is off you can't feel the car's power transfer. So you have to keep looking at the display and not at the road. And last, but not least, I was relieved to have a car come up behind me. I was driving on roads with 35 - 45 mph speed limits. To accelerate to 41 and then slowly decelerate to 25 or 30, just to repeat the process is quite annoying.

Conclusion - I'm glad I did it. I got a nice (although short) high mileage run. Doubt I'll ever try it again.
