01/01/2005 through 01/20/2006
Mondays: 25 up days, 21 down days (4 more ups than downs)
Tuesdays: 26 up days, 29 down days (3 more downs than ups)
Wednesdays: 30 up days, 25 down days (5 more ups than downs)
Thursdays: 29 up days, 25 down days (4 more ups than downs)
Fridays: 29 up days, 24 down days (5 more ups than downs)
Summary:
Only Tuesdays had more downs than ups over the past year, and only by a margin of 3.
Conclusion:
There may be some other factor I'm not taking into account. Otherwise, I can't see a value in starting the day with a bias based on the day of week.
