What's your average MPG for your 370z?

So, I've had my 370z Sports + Touring + NAV, 6MT for a month now, and I've been getting some pretty ridiculous MPG since. I've been driving 3/4 city and 1/4 Hwy and I always leave the A/C on.

For the first 500 miles, I've been shifting before 3000-3500 RPM. And the AVG MPG registered at 15.9.
Then for the next 500 miles, same case, but I would shift in the range of 3000-4000 RPM and it's starting to pick up to 16.5 MPG.

Finally, after broken in my car at 1200 miles, I would shift within the range of 3000-4500 RPM and the best I got was 17.4 MPG.

I would turn off the A/C and it wouldn't make any difference with the MPG, I'd drive 1/2 Hwy and 1/2 city and it's still 17.4 MPG. My AVG speed is 26 mph.

The MPG rated for this car is 18 city and 26 for hwy. To be honest, I was expecting this car to be in the middle of the 2 MPG. Somewhere around 20-22 MPG, but it seems like I'm not even close.

Sure I understand, I'm driving a Manual transmission so I'm not gonna get as good of a fuel economy as an Automatic transmission considering they tweak these AT parameters optimize to be as fuel efficient as possible. Also, I have the A/C on all the time.

But here's another comparison, my other car is a 2007 Lexus IS250 AT. It's rated at 21 city and 29 hwy. And I've been also leaving the A/C on always, similar amt of city and hwy driving, but I'd always get around 25 MPG (right between the two rated MPG. How's that the case? Is it really because AT is THAT efficient? Or is it because it's a Toyota/Lexus? Or is it the way I drive?

And if it's the way I drive (and I consider myself driving really easy on the throttle most of the time), what's the best MPG are you guys getting on your 370z?
