Why do ties count as a loss in the winning pct?  Shouldn't a record of 10-4-1 be the same as 10-4?  .714

I checked the link provided, and the answer inidcates a percentage different than the one you posted.  The link provides the following answer:

In sports, a winning percentage is the fraction of games or matches a team or individual has won. It is defined as wins divided by the total number of matches played (i.e. wins plus losses). A draw counts as a ½ loss and a ½ win. Winning percentage is one way to compare the record of two teams; however, another standard method most frequently used in baseball and professional basketball standings is games behind.

For example, if a team's season record is 30 wins and 20 losses, the winning percentage would be .600. If a team's season record is 30–15–5 (i.e. it has won thirty games, lost fifteen and tied five times), the five tie games are counted as 2½ wins and 2½ losses, and so the team has an adjusted record of 32½ wins and 17½ losses, resulting in a .650 winning percentage 

So, if a record is 10-4-1, then the tie game is counted as 1/2 win and 1/2 loss.  The adjusted record would be 10 1/2 wins and 4 1/2 losses, resulting in a winning percentage of .700.  You have it listed as a winning percentage of .667

Ok, I see the problem. You are configured with "Exclude Thursday game" which is a new feature and you indeed have identified a bug as its including the Thursday non-game in the calculation. Note that it displays properly if you use the "This Week" radio option. 

I'll have a fix for this for week 2 going forward.

Do you recall changing the setting "Is no pick a loss" from yes to no? It will help me pin down where the calculation went awry. Thanks,

Hi Eddie... No need to reply to last post, I figured out where the problem is. It's fixed now. Thanks for letting me know!
