...The competitor whose score after System Testing is the closest to the average of all the scores in Round 1C.

Week #7 Challenge

For the seventh week, we go back to the Marathon Competition. Marathon Round 2 has started, and the seventh t-shirt will go out to...
...The competitor whose score at the Marathon Round 2 mid-point has fractional part* closest to the average of fractional parts of all the scores.

I’ll get a snapshot of the leaderboard as close to the mid-point as my schedule permits. Submissions made but not processed by this time will not be included. In case of a tie the earliest submission wins.
*Due to the discrete scoring system used in this problem the fractional part of the score will be defined as the last 5 digits of the score, i.e. three digits before the decimal point and two digits after the decimal point (of the 5 digits after the decimal point of the score divided by 1000).
