Has anyone calculated there actual $ savings by Eco-driving?

I am going to fill up this evening on the way home - first tank after discovering you guys - and I was thinking, is there a way to quantify the actual impact in terms of $?

Here is my thought.
My last tank ( pre ECO) was 22.4 MPG
lets say this tank is 25 MPG. ( 300 miles and 12 gallons)
and fuel costs $3.00 USD / gal

my Actual bill is 12 gallons x $3 / gal = $36
had I been driving the OLD way = 300 Miles @ 22.4 MPG = 13.4 gal
and I would have paid 13.4 gal x $3 = $40.20

Thus i have saved $4.00 this tank. only changing my driving style

Calculate that over a year for each tank-full and there is you ACTUAL fuel cost savings

Granted the 22.4 mpg was 1 tank and things will vary over time - but this would make it seem more "REAL" from a $ standpoint.

Do you guys do anything like this to track $ saved?
looking at some of the MPG's - I would think it is pretty high.
