Contest winner's page messed up

Contest

The contest winner's page is messed up, with Michael and Szilvia trading places for which month they won. Szilvia Hegyi's performance and balance are not consistent with her balance quoted at $91,477.41 and her performance showing as -1.43%. Simon's performance and balance have not changed in almost a month and Spencer's performance started showing change yesterday, mid-month. It makes me question the entire performance reporting software.

The most basic task of the quantitative manager is accurate performance. What's up Q?

Indeed. Also, the score in the Quantopian Open contest page is missing the Beta criteria and is messing up the entire ranking system. Please do not make changes to the jugding criteria of an ongoing contest. You will lose credibility in this case.
On the other hand, thank you for the great opportunity you are giving us, the passionate trading systems developers.

Another weird thing. My post shows " Sally Sanford edited Yesterday", but I didn't. However, the tags changed on my post from a bunch of tags to just one now.

Did the Q staff edit my post? Or an I losing my mind?

We're in the midst of updating the contest pages. Stay tuned. For the latest work, see here: https://www.quantopian.com/open

The beta-to-spy criterion is still a key metric for contest algos, check out the "Judging" and "Criteria' section of the contest page. The main recent announcement was all entries will develop 6 months of paper trading track record. This helps to showcase the algo and demonstrate the out-of-sample behavior. And I noticed your algo is doing well in the contest - good luck in the upcoming months of paper trading!

Thank you, Alisa! I talked also to Dan Dunn, please tell him that the problem with the leaderboard page is beginning with the missing betas in the database, as I saw it in the October Contest's leaderboard-1442972461.csv file:

I'll dig in to see why the beta-to-spy isn't get populated in the CSV's.

Cheers,
Alisa
