Sorry for late response…
I think there is a confusion.
Submission phase
The submission phase is from May 16th, 2023, 05.00 PM CET to August 16th, 2023 04:59 PM CET which is 12 weeks.
In the submission phase you are scored on the date 269 to the date 299. The mean of your scores is not taking into account the first five dates though as they are available for you to test through the cli crunch test
Out-Of-Sample (OOS) phase
The OOS phase is from August 16th, 2023 04:59 PM CET to November 16th, 2023 11:59 PM CET which is also 12 weeks.
In the OOS phase you will be scored on the date 301 to the date 335; So 35 date in total.
Each week of the OOS phase the leaderboard will be updated with 3 new date (2 for the first week). Your mean score each week will be an average of your computed score (eg. date 301 to date 305 included on the second week leaderboard).
I hope this answers your questions.
