I don't have back to back comparo data with "foot" vs "cruise". But I think the key here is *hills*. I was traveling from Seattle to Eastern WA and there's 3 big ranges to go over. What happened; I would fill up and be going along at 70+MPH getting 35+ (on the read out 35-38mpg) with my *foot* but then as soon as I put on cruise control the readout just started dropping: 36, 35, 34, 33, 32.. then level off. This was the same for the trip out and the trip back.
BTW: when I fill up and do the manual calculation my Avg MPG readout is consistently .7-1.3 mpg high compared to real world calculation. I always reset my avg mpg readout with every fillup. On a clear traffic time of the day I can drive from Everett to Puyallup (about 70 miles) and get 36-37mpg with my right foot doing 60-65mph.
Not the data you wanted to look but I hope this helps.
