Inaccurate mileage b/c of "week" rule

I didn't realize that you had to log all your miles within a week of riding them...so now I'm completely blocked from including the week of May 17-23. This seems to be a disadvantage not only to team riders, but to Bike to Work Day efforts as a whole - I logged at least 30 miles that week and if there are others who also had a busy week at work and couldn't keep up with the clunky web form, you're going to be low on your count for how many miles we actually did ride. I would think that a lot of folks would lose steam on the data entry towards the end, and find themselves in a similar situation. Now I'm frustrated looking at my calendar and knowing that I was bike commuting all those days but the computer won't let me enter them! But I guess it's just like the other 11 months of the year when I bike to work without motivation or reward...
