Very unscientifically, I find the dumb cruise control to be more efficient than propilot.
I agree that in the S+, the efficiency difference between 55, 60, 65, 70mph is tighter than in the SV+. In the SV+, on anything but a super hot day, you are in the low 3s at 70mph+ (unless driving with a pack of cars/trucks). At 55mph you are in the mid and sometimes upper 4s. In the S+ at 55-60mph you are around 5 miles/kWh and down to mid 4s at 70mph.
I am starting though also not to care. As long as I can do over 200 miles on a charge at 70 (which the S+ can in most weather), there is not much else I need the car to do. I do want one major car review site to range test the S+, but not sure that will happen.
Interesting findings, however anecdotal.
I'm a little surprised that the S+ is that much more efficient than the SV+. It's not like the one weighs that much more, and even if it did, you're mostly talking about more or less steady state driving, aren't you?
Our SL+ routinely gets mid 4's, and I'm not working at it in the least. I drive the car like my other cars, precisely because I want to know what it can do under similar circumstances/driving styles. I average 4 even for the whole year with my driving cycle, which is almost exclusively in town, very little highway. I do run snow tires in the winter, and have moved the stock all-seasons to new wheels, which are not aero (but are 5# lighter each).
To your point, the car gets me to where I want to go. That's all that really matters.
