Occam's razor doesn't suggest that. It suggests you eliminate all NON INFLUENTIAL variables. Like your hair color. It does not suggest eliminating variables such as wind, temperature, driver skill etc.
It is great to know the sweet spot, but that isn't the most important factor for FE. In fact, It is becoming common knowledge that doing a pulse and glide at most acceleration rates doesn't realy make that much difference.
If you just want to set your cruise control and take what you get then your chart is good at showing what to expect. It is not good at showing replacement of a drivers skill because the two are not comparable.
What you need to do is add the lower speeds to the chart and find out where it levels off at the low end. You might fnd around 20mph mileage drops off. Then you can get your peak. This will be the most a driver can get with cruise control. I'm betting it will be a bit lower than what a skilled driver can get.

Re: Hypermilers Attempting FE Record in a Honda Insight
I'd like to suggest going beyond civility and have a truce.
It's apparent the inquiries for data are not coming from a dispassionate mind, esp. when it concerns a vehicle other than a Prius and perhaps hypermiling from reading his posts since last night. I see no point in pitting one 40mpg+ vehicle against another - there are not enough of them.
bwilson4web, it's likely you knew about the Insight Marathon before the event surfing CleanMPG - that would have been the best time to make suggestions on data to collect.
Truce bwilson4web please?

Delta, I don't think you could make the assumption he knew about it before hand. I'm sure if he did he would have made the suggestion.

Re: Hypermilers Attempting FE Record in a Honda Insight
It's very possible Tom, but a recent post suggests he might have been looking there (concerning one of his complaints).
Just the same, hoping bwilson4web and I can mutually agree to do posts that are more postive than the ones in the last 24 hours and agree to disagree on some things...

The lower range needs to be mapped. We do have a simulator plot but I prefer to benchmark the performance.
As long as there is no minimum speed for a vehicle endurance run, one might as well try the maximum MPG, endurance speed but it would be boring. It would be safer to automate everything and just monitor the systems.

Re: Hypermilers Attempting FE Record in a Honda Insight
I think you all are not understanding what Bob was saying. I think what he is getting at is that if the steady state mpg at say 20 miles per hour is 115 mpg, and the guys got 170 mpg at an average speed of 20 miles per hour than driver skill is worth 170 - 115 = 55 mpg. OTOH if they got the same or less than steady state than they might as well just have set the cruise.....
How I'd do with the translation to normal people talk?

Re: Hypermilers Attempting FE Record in a Honda Insight
Sounds good. I guess I just don't like to equate cruise control with skill. Maybe I'd be happy if it was A drivers skill is worth 170mpg and cruise control is worth 115. One doesn't replace the other. They are apples to oranges. By saying the drivers skill is only worth 55mpg is assuming cruise control is part of the equasion which is very rarely if ever is the case. so drivers skill = 170mpg cruise control = 115mpg. Not drivers skill = 55mpg and cruise control = 115.
Does that make sense?

Re: Hypermilers Attempting FE Record in a Honda Insight
I've been "doing the math", here are the results so far:
Day1
11 hours 20 min (680 min)
258.9 miles
22.84 miles per hour/D1
Day2
14 hours 30 min (870 min)
284.6 miles
19.63 miles per hour/D2
Day3
13 hours 24 min (804 min)
239.9 miles
17.90 miles per hour/D3
Day4
14 hours 19 min (859 min)
254.2 miles
17.76 miles per hour/D4
Day5
12 hours (720 min)
205.9 miles
17.16 miles per hour/D5
Day6
16 hours 29 min (989 min)
287.6 miles
17.45 miles per hour
More to come.......
Day7
22 hours 8 min (1328 min)
380.2 miles
17.18 miles per hour
Day8
12 hours 38 min (759 min)
208.4 miles
16.47 miles per hour
Day9
8 hours 18 min (498 min)
134.5 miles
16.2 miles per hour
Totals:
2254.4 miles
125 hours 07 minutes (7507 minutes)
18.02 miles per hour
