Just curious, if you go to maps.google.com and get directions for your bike commute, how accurate is the elapsed time that google estimates for the trip versus your actual time? You can pull the suggested route around to follow your actual route, you might have to turn on the bike route options for the map overlays.
For one route I'm looking at, google maps is saying 14.6 miles and 1:25 for the time, which is somewhere around 10-11mph average allowing for stop signs/lights. Seems low, but maybe not. I guess I should go check out the "how fast" threads, but I was just curious specifically about the Google Maps bike routing function. Granted it is all relative, and different people ride at different speeds, and I don't know if the utility calculates in hills and such.
I was going to try using the Poll option, but can't get it to work on this computer. So how about giving your actual time/distance and then what Google Maps comes up with. I'm going to try and get out for a non-commute ride this weekend and see how close it is.
