It just makes more sense to ride after work, in better wind, for most people. This change of time takes that option away.

The wind doesn't usually even fill in (yesterday was a classic example) until about 45 minutes after the sun comes up.
And that's usually only for about an hour. Check out 5pm for yesterday.
Oh well. I hear ya', I have done my share of DPs, I just think the wind in the afternoon is more consistent and more predictable, especially the last couple of seasons. It use to be the other way around.
