Pros and cons of driving in ECT Power mode

the 430 manual warns about decreased gas mileage in the PWR mode.
I was surprised to find, not only performance improvements, but better gas mileage.
what's up wid dat?
and is there a method to optimize the programmed PWR performance?
the car's chip monitors driving habits.
are there a specific ways to trick the PWR mode into even better performance?

I conducted a test checking MPG in each mode.
After four gasoline fill-ups in each mode, the MPG was the same; no increase or decrease in MPG.
For the entire life of my SC, I have averaged 15MPG from the first fill-up to the present time driving mostly stop and go on city streets with very little freeway driving.
Because I prefer having the extra pickup power, I keep the PWR mode on at all times.

I was getting an average 21 mpg in standard mode.
PWR mode now yields an average 22-24 mpg using trip monitor.
as for rating mpg using the 'old method' how would you accurately
gauge the precise distance v. number of gallons used?
mileage yes, but how do you accurately apply that to actual gallons?
please explain.

For instance:
-You fill your tank with 15 gallons (make sure your tank is full)
-Your trip meter says you have traveled 250 miles
The equation would be 250/15 = 16.66 miles per gallon

The tricky part is filling your tank to the same level every time, unless you fill it to the point where you can actually see the top of the fuel.

Fill it up. Restart trip odometer. Next time you fill to top, divide miles driven on odometer by gallons filled. DONE.

now that makes sense.
I'll try it, but I'd hate to have my 24.4 mpg bubble burst!

The problem with that method is that it doesn't give you the true gas mileage. It only tells you what the mpg was for the amount that you put in the tank. I've noticed that on a typical fillup on my SC430 that I can add as much as 1 1/2 gallons after the pump initially stops. That leaves a lot of room for error, something like plus or minus 7%.
