AdventOfCode'2017 Custom Leaderboard


This is a version of a leaderboard which counts only a time between receiving first and second star (only compares time spend on a task number two in any certain day).
The leaderboard therefore is not connected to the time participants started their first task, which makes it possible to get places even if you can not start at midnight EST.

This leaderboard differentiate between participants who solve tasks using their own coding and problem-solving skills and those who rely heavily on AI tools for rapid automated solutions. While the latter group is excluded from this leaderboard by default, their results can still be viewed via a provided link.
