^ The thing is that using the wrong terminology changes the entire statement. You have to be specific with your words so that your meaning will get across.
The throttle controls how much air is allowed in the manifold, and is limited by the intake piping/filter. The TPS (Throttle Position Sensor) tells the ECU how much air should be there based on the size of the factory manifold, and the ECU pulses the injectors more or less based on that position. That's also limited by the fuel rail, pump, filter efficiency, and the injector itself.
If you want to go and save gas, a K&N drop-in panel filter, removal of the intake resonators, and over inflating your existing tires to 36PSI will give you a noticeable improvement, all for about $50-60.
What are your goals? Better to get that out in the open so we are on the same page. If you're going to try to make the car your super gas saver, then do the above and use nitrogen in the tires, lose any extraneous stuff in the trunk, etc., don't drive fat friends, the list goes on. Basically try to reduce your mass by as much as possible without compromising safety and not only will you burn less gas, the gas you do burn will be used more efficiently, which leads back to burning less gas again.
Acceleration up, gas consumption down. Then since the car has less mass, it will stop easier, too, using the OE brakes. You should know this since science is your forte; this is physics.

I love the concept of Nitrogen filled tires. Not only are nitrogen molecules larger than oxygen and thus have a slower leak, but the gas is inert and therefore doesn't damage the rubber from the inside-out.
LMAO, don't drive fat friends... I cannot pick my passengers, but I try. Yes, science is my forte... I'm a biotechnician with a love for biology and particle physics... ;D
Talk nerdy to me, and we'll get along just fine. I am just a bit alien to this automechanics..

As for the parts I highlighted in bold... that's child's play and implied... please don't patronise me like that.

It's not what I was doing, but I figured I'd cover my bases and guarantee that anyone else reading the thread would understand.
I got the same feeling when you posted the "picky picky" comment, but I held my tongue.

As for applying personally to my car... that is what I am doing.. I'd need to practice my knowledge on cars before piecing the concepts together.

I just remembered I'm a bit hesitant to push the envelope with PSI in either direction.. too much or too little... because of the pressure change that acompanies altitude changes...

Not to mention improper tire wear. 36 psi isn't too bad but I wouldn't go much higher, especially if you drive beyond 75 mph.

I try not to accelerate too fast due to wasting gas with too harsh rpms... but when I plateau on top speed... it is well over 75mph.. I avg. 90-110mph on the freeways... plus I bend concrete with my turns.

The goal is... hard to explain. First and foremost it is to protect the passengers; from any and everything (i would get bullet-proof armour but I don't have the engine to achieve such a goal--plus that would contradict the second goal); fuel-efficiency, not just to save my pockets... but to help promote a greener earth, I'm an environmentalist looking out for the future of this planet... which goes back to the first goal of protecting life only this is protecting the life of my friends and family down the line future-wise. I am a guy that likes options too, hence why I went with a Honda make... not American. I like modular devices as well, and versatility. This is why I desire to take this car to extremes like off-road and over islands... just in case. Basically, this car is a one-stop-shop for any occasion.

I always check my gas mileage every time i fill up and I average between 21-23mpg between city and highway but on a road trip the best i ever achieved was 26mpg cruising at 70mph

I've been driving more hwy miles lately since moving and have been consistently hitting over 24.6 mpg in the last 2 tanks. I hope it keeps up 
but winter is coming up...more warm ups, more traffic, etc...probably going to go back to 21-22.

Heheh, I can't wait until my first refill. I'll be playing this little game, too.
When I had my 96 Infiniti J30, the best I ever got was 30mpg, which was clearly wrong, since the car was rated at 24mpg max highway. I think there were a great deal of additives in the fuel to make it do that. After that, the best I had was 23.8mpg. Oddly enough, it didn't seem to matter on highway driving how I drove, I averaged about 23.2 highway.
I brought my new 3.2TL home about 160 miles from the used dealer. Still sitting above half a tank. I'll post when I do my first refill.
