For first 700 miles on my Tiptronic Cayman, driving almost exclusively in suburbs, I averaged 20.3 MPG.

Mine, Cayman S, 06, Tiptronic, average about 18 - 21 mpg. This is with a lot of heavy back to back freeway traffic during the week. With occasional fast highway driving. I do try to watch the mpg and not push the car agressively when I am stuck or have no chance to drive fast. But when the road opens up, I do push it.

You really do have to specify your type of driving, how much of each, etc., to get a good sense of how your average can compare to thers' averages. Or, you need to specify your mileage for each type of driving condition. What a mid-Western city may have for "city" driving will be way different from my Silicon Valley morning commute. Driving interupted by stoplights is much different from 20 minutes of crawling at 5-9 mph.
Having said that - I've not reset my mpg reading in the last 3000 miles, and I'm averaging 20.9 mpg. sometimes it reads as high as 21 mpg. I have a 2.7 with the 5-speed manual transmission.
Of the 3000 miles, I've had perhaps 1200 miles of true highway cruising (at normal frewway speeds a bit over 65mph), another 800 or so of somewhat more aggressive driving, and the last 1000 miles in my (almost) daily commute drive of 16 miles each way.
The commute drive does the most damage to my mileage. Of the 16 miles, I spend approx. 6-7 miles (8-9 on a really good day) at 60 mph. About 6 miles crawling and bumping along at between 5-15 mph with a lot of idling time. The rest is city streets with the normal complement of traffic and stoplights.
Based on observation (not rigorously documented) I think I get about 15 mpg in the stop-and-go crawl, 20 on the street with stoplights and 23-25 on the open road. The open road figure is borne out by distance and fuel load readings when doing my long drives.
