[edit] Reading View User

Each song shows the score entries for each difficulty entered:

• The top line shows the difficulty (linking to the View Song page for that song/difficulty) and a double arrow if you're on your own page to link to session mode. This way the View User page can be used as an alternate session mode.
• The second line shows your grade.

On the right column of the page, you will see a number of metrics:

• User name, Popper name, and what type of controller this person uses.
• Songs within "striking distance", that can be easily raised.
• The last 10 songs you've entered scores for.

You can filter down the view by using one of the style filters in the top right.

[edit] Striking Distance

A song is considered within "striking distance" if you're within 500 points of the next grade level. While there's been some debate over the merit of this number, it's generally considered to be a reasonable enough gap that you could luck yourself into if you played the song enough.
