WHAT TO WATCH

Landing Q and taking Q are separate decisions.

The pack separates aim from commitment and measures how long Lee Sin uses the mark window before going in.

Early dataWe wait for enough players before calling something a benchmark.
Exact actions measured One score per player Compared by current rank Missing evidence stays unavailable
q execution

Q1-hit to Q2 delay

What it measures
Q2 delay distinguishes immediate commitment from patient use of mark duration for damage amplification, cooldowns, positioning, or enemy reactions.
Why it matters
This is a decision and style metric, not a simple higher-is-better score. Use its position in the field to find unusual tendencies, then inspect the situations producing them.
MASTER0.86sn=21 · 30 eligible games · early sample
GRANDMASTER0.94sn=23 · 37 eligible games · early sample
CHALLENGER0.82sn=27 · 57 eligible games · early sample
Observed medians run from 0.82s in challenger to 0.94s in grandmaster.

71 players across 124 eligible replays in 3 ranks.

Curves show observed player distributions. Anything the AI could not see in the replay is unavailable, never scored as zero.
LEE SIN REPLAY LAB

Marks, recasts, passive cadence, and kick sequences by rank.

645 ranked-solo AI-watched replays from 270 current-rank players; 71 players have verified spell-event metrics. Curves are preliminary because no tier reaches 30 spell-covered players.

How Lee Sin mechanics are measured

Seven scores calculate now. Ward hops, energy realization, insec geometry, kick value, jungle tempo, and fight entry/exit remain withheld.

MECHANICS LIBRARY

The Blind Monk, made measurable.

01Observed

Q2 patience

A landed Q creates a decision window, not an automatic instruction to commit.

Measured as
Seconds from replay-confirmed Q1 contact to its one-to-one Q2 recast.
Training drill
Review every Q2 under one second and label safe, necessary, or rushed.
02Contextual

Flurry cadence

Two autos after a spell can recover energy and accelerate clears, but maximizing the rate can be wrong in danger.

Measured as
Eligible spell windows followed by two attacks divided by all eligible windows.
Training drill
Run one clear while deliberately counting two autos between abilities.
03Observed

Q1 contact

Separates getting a mark onto a champion from what happens afterward.

Measured as
Attributed champion contacts divided by tracked Q1 casts.
Training drill
Classify misses as blocked, prediction, range, or rushed.
04Observed

Kick sequence identity

R→Flash and Flash→R are mechanically and tactically different sequences.

Measured as
Each sequence counted from deterministic spell order and timing windows.
Training drill
Rehearse both directions and review the chosen order, not only the outcome.
MATCHUP APPLICATION

The same score can mean something different by lane.

GAME PLAN

Use the mechanic for the right play.

Clear rhythm

Flurry is an energy and tempo system; compare cadence without turning it into a maximize-at-all-costs score.

See the matching mechanic

Late fights

A technically valid kick is not necessarily valuable. Displacement geometry stays withheld until the AI can prove it from the replay.

HOW WE KNOW

See exactly what is measured.

We show patterns only after enough real players support them. Early results stay labeled, and missing information stays unavailable.
