Base rate, then community votes
New peeks start with an estimated grade from a base success rate. Once enough players vote whether the peek worked or failed for them, the estimate is replaced by the live result: the share of worked votes, mapped to a letter grade (S+ through F).
Grades keep moving
Every new vote can nudge the grade. That is intentional — a peek that was free last month may get pre-aimed after it goes viral. Open a peek page for the current grade, vote count, and clip.
7-day trend arrows
On list pages like Top peeks, a red down arrow means the angle has been working less often over the last 7 days than the week before. Use that as a warning, not a ban — some peeks still print in lower ranks.
