Basics

Sorting is done by selecting (clicking) the better of the two episodes on top.

You can see the episodes that are next in line for comparison below the first ones. If you have been responding truthfully, the best episode should always be on top, but you can choose whatever episode you want - because mistakes do happen and because comparing by feeling isn't perfectly transitional. If you really can't decide, you can give the two episodes on top the same rating by clicking I'm an indecisive beta cuck.

You can also use undo to fix your mistakes (up to 10 steps back).

Save/Load

The page automatically saves your progress and loads it when you return. You can also use the save/load buttons (you may want to use that to make sure that your last decision was saved, and to load the autosave after using reset).

You can also save the progress by using export (this is more reliable, as can't loose your progress by clearing cookies or something like that).
