using these techniques makes a big difference indeed!
on the highway in 6th I now stay under 3k rpm (70mph) - the energy required to move my little brick through the air increases as the square of the speed, it is not linear
shortshifting, featherfooting, skipping gears, looking ahead - all have contributed to my average mileage jumping from 26mpg (300 miles 'till a fill as I don't run it down all that low) all the way to 33mpg (360 miles on 11 gals)
as I drive about 20k miles a year, my savings annually are in the order of $700 dollars (assumes $4.20 per gal)
what I don't do, is slow down for the corners much... what I do do (doo-doo?) is stay closer to the speed limits than I used to...
considering that the fun factor for me is cornering, I give up very little fun for one heck of a savings.
on my current tank I just hit the halfway mark with 270 miles traveled...on a refill I came up with 307.5 miles traveled on 9.48 gallons, for 32.4 mpg
of course the Mini gas guage is pretty special - mine records about two thirds of the actual fuel used as the "upper half" and the remaining third as the "lower half"

If I didn't know it, I would have sworn that you & I have nearly identical driving patterns with the same results & data. Good post!
