Reflex checks need wider timing window options

What it is

Reflex checks (parry windows, dodge judgement, rhythm hits, frame-perfect moves) succeed only when input lands inside a window measured in milliseconds—a direct test of reaction speed. Wider timing windows scale the window up (×1.5 to ×5) so players whose timing works differently—longer reaction latency, unstable timing estimation, higher-input-latency devices—can still play timing gameplay. Compared with auto-execution (skipping judgement entirely), widened windows preserve "I pressed at the right moment" participation, making them the first-choice accessibility instrument for timing gameplay.

Why it happens

The window barrier comes from the individual distribution of reaction timing. Simple visual reaction time spans roughly 200-300 milliseconds across people (individual difference plus input and display latency widening it further), while hardcore action games' perfect windows often sit under 50 milliseconds—the window width itself is a filter that screens out players on the right tail of the reaction distribution (not less skilled, physiologically different). Widening moves the filter line from "physiological reaction speed" back to "learning the timing": at ×3, what demanded reflex becomes a press guided by rhythm prediction—learning remains (when to press), execution tolerance grows. Window tiers should cover "slightly slow" through "reaction unusable": light widening (×1.5) serves slightly slower players, deep widening (×3-×5) serves high-latency devices and severely limited reactions, and the top tier approaches auto-execution's effect while keeping the press's participation.

Where it stops holding

Window widening's ceiling depends on genre: where timing precision is the core play (high-difficulty rhythm charts, fighting-game frame-perfect links), full widening means a different game—the correct approach is parallel difficulty layers (a wide-window chart alongside the original, not a modification of it), preserving the original chart's challenge identity. Widened windows need honest visual feedback: successful hits should distinguish "wide-window hit" from "perfect-window hit" (scoring separation), otherwise widening reads as "the game got easier" rather than "tolerance grew." In networked games, window widening also interacts with latency compensation (aligning client windows with server judgement), requiring server-side synchronisation. Perception management matters too: visualising the judgement window (hit-region indicators) alongside widening lets players see where their input lands, turning "rolling the dice" into "visible timing adjustment."

Applying it

• Provide a window-multiplier setting for reflex judgements (×1/×1.5/×2/×3/×5), applied globally with per-mode overrides.
• Separate hit-quality feedback (perfect / good / wide-window hit), and keep the top rating reachable at narrow windows so experts can still chase perfection.
• Verification: compare reaction-limited players' judgement success rates and subjective rhythm ratings across window tiers. Success approaching standard-window players while rhythm ratings hold means widening achieved "the same play at different speeds."
