Portal 2 Least Portals Leaderboard

This is indented to be an independent, uncensored and (somewhat) moderated leaderboard with records history, pretty graphs and statistics.

Rules

Use common sense. You can use any non cheat commands as long as you can complete the same tricks easily without them.
This means commands like cl_interp and r_portal_use_pvs_optimization are okay, and commands like give and net_fakejitter are not.

Last update

Partial score updates happen every hour, and complete score updates can take up to 3 days.
