Not at all. If you'd like to
really thank me, since I increased your mileage by 61.1%, give me a 'reputation' point - I'm tired of seeing myself stuck at '1'... ROFL...and thanks.

Yes. I was remiss in not noting that you're on your 3rd tank. My apologies. At 18mpg, that's roughly 750 miles, at 14 gal fillup (guessing, based on my usual - ignore the '17 gallon' rating...that's for another thread

)
At that mileage, you're doing pretty good with 29-30mpg. You should notice a little increase with this tank (obviously, given your 100 @ 29, but I mean as a result of break-in, for everyone's AH). Your next jump (and this will probably be the largest) will be between 1200 - 1700 miles. That's when your initial break-in will be completed (this may vary for you, given your short trip / low speed commute).
After that, you'll see (much) smaller increases after 3000 mi, then again at 5000, and then finally at 10,000 (based on my / others' experience with Honda's J30 V6; I've only got 7600 on this one so far

I'm talking tenths here; the one at 1700 should net you 1-2mpg, if my experience is typical.
Next, we'll address 'practice'. Keep up with this, and you'll net yourself another 1-2mpg, as you get better.
Finally, consider increasing your tire pressure by 5-6lbs, as less rolling resistance will net you 1-2 mpg on a tank. If you tolerate that loss in ride comfort well, consider 40, and then 44. I don't use 44 myself - it's a bit harsh for in-town. But there's a thread here that shows a 45+ mpg segment obtained by Xcel and myself from Gurnee, IL <> Madison, WI. That was done with 44lbs in the tires, and since it was all highway, it was tolerable. I run about 38 now.
Good job, and have patience. It takes time to learn a new style of driving, and forget everything you knew about driving to a speed. You now know some extent of the possibilities. Enjoy the car - I know I enjoy mine - and don't forget to add your car to the mileage database, now that you've broken the 20mpg barrier
