27.2 - 95.3 (22/32/44 x 12-21 7 speed)
If this bike was just for commuting I'd keep that range. But since I use it for other things, and I've hit some ridiculous hills, I'm going to get my gearing changed to this in a few weeks:
21.2 - 95.3 (22/32/44 x 12-27 9 speed)

Don't know exactly, it's way broader than I need. My main commuter is a Surly LHT. Could use either the big or the middle ring for the entire commute.

Sturmey-Archer SRF3: all in gear inches.
Low (75%): 54
Unity (100%): 72
High (133%): 96
99% of my riding is in the middle gear. (Old SS/FG habits die hard.) That will change once I start towing both my kids around. Even then, I do not envision much use for the high gear.

Built up my 700c LHT this spring. Mounain crankset and 8 speed cassette ===> 19-103 gear inches.
99+% of my commute is spent between 43 and 75 gear inches. The low gears are there for hills on tour.

22.2 - 117.8 , 11-34 48/38/28. I had a 7 speed 13-30, but when I went to 9 speed (for equipment availability reasons) I didn't mind the existing ratios so I just added a lower and a higher. On my commute I don't use the 28 ring; it's for towing the kids.
On the flats I end up about 65 (stopped at lights)-100 inches; hills bring me down to about 35. If it weren't for the occasional towing a 1x9 would be great. Certainly I could live with a compact double.

Commuter is a single speed @ 73 gear inches. Hills are challenging but the biggest issue is that I spin out above 25 mph. Still a good compromise and love the simplicity. I have been told that when I hit 60 later this year, I am obligated to either go multi-gear or change my 46t chainring to a 38 (for 60 gear inches)
I sure would like to have a "Friday" gear though. Friday is the day that I haul all my dirty laundry home - adds maybe 20 lbs.

38-116 gear inches (53/39 front, 12-27T back)
I use them all each ride and still run out of gears at both ends of the range.

An easier example to explain: You know going from 50 to 100 would be 100%, correct? It's ((100/50) - 1) x 100 = 100% NOT (100/50) x 100 = 200%, though 100 is 2 times greater than 50.
Steely Dan is off by 100 percentage points, too.

Assuming I'm reading the calculator correctly, 23.6 - 117.8
Tires: 700x32
Crank Length: 175mm
Chainring:48/38/28
Cassette:11 13 15 18 21 24 28 32
I never use (well, after 3 weeks I haven't yet), the big ring or the small ring. I tend to stay in 1st to maybe 7th? on the middle ring, with the majority being 3-5.
Hmm, I think I could have saved some money on my new bike and gone with a 3-speed

according to shimano, the manufacturer of the Alfine 8 hub:
The inter-8 hub has increased its gear ratio to 307%, compared to 244% of the Inter-7 hub. The Inter-8 hub also incorporates a closer gear ratio allowing a more efficient and comfortable pedaling cadence. A trully "all conditions" internal hub has arrived.
the gear inch calcs i got from sheldon brown's site were off by 1% for the alfine 8, not 100%.

Gear range is calculated as high/low*100, or put another way, the highest gear is x times higher than the lowest gear.

17 - 115. I normally only use the middle chainring for my commuting route, though.
