Not enough trace coverage yet. Historical rating traces are currently tracked for the top-100 active NCA players. As your event history grows, your past traces will appear here.
The yellow line is the system's current best estimate of your skill at each point in your history — a smooth arc that reflects everything FlickSkill now knows, with the benefit of hindsight.

How the chart is built

The yellow Skill Arc is FlickSkill's current best estimate of your true skill at every point in your history — a smooth curve fit across all data, including events that happened after each point. It's the most accurate retrospective view, but it keeps moving every time the system learns from a new tournament.

The green Published Rating is what the leaderboard showed at the time. Each green dot is the endpoint of TTT's view right after that tournament was processed, with no future data yet — that's the rating you would have actually seen on the public page. The green line never moves once an event is locked.

The gap between green and yellow at any event is how much FlickSkill has re-learned about your skill since — wider gaps mean later results pulled the system's view of that event up or down. Hover a point to see both values plus the felt change since the previous event.

The blue dotted lines are past traces — each shows the full Skill Arc as FlickSkill saw it after a previous tournament. The slider controls how many overlap. Together they show how the system's view of your whole history evolves over time.
