Reactions and Perceptions

## Reactions

In the realm of fiction, the way characters move and react over different distances can vary significantly, leading to notable disparities in their overall speed. To address this, our wiki recognizes and distinguishes between various types of speed, including reaction speed.

Reaction speed refers to a character's ability to execute a single movement within a specific timeframe, as demonstrated in their feats. It represents their capacity to swiftly respond to stimuli or threats in a quick and precise manner. This term should be used exclusively for individual, rapid movements, rather than a series of actions over time. Examples include evading bullets by swiftly ducking or quickly diving away to avoid fast-moving vehicles.

When considering a character's reaction speed, it is typically measured in terms of a single movement covering an undefined, often small distance. For humans, the range of reaction speeds displayed in fiction can vary. Below-average humans have been shown to possess reaction times of around 300 milliseconds, while peak humans can exhibit reaction times as fast as 100 milliseconds. It's worth noting that autonomous body reactions, which can occur as quickly as 40 milliseconds in humans, are generally not applicable for determining reaction speed and should not be used as a basis for comparison.

It is important to recognize that reaction speed is just one aspect of a character's overall speed and combat proficiency. Other factors, such as movement speed and agility, also play significant roles in combat effectiveness. Therefore, a character's reaction speed should be evaluated within the context of their overall capabilities and the specific feats they have demonstrated.

By understanding and differentiating between the various types of speed, including reaction speed, we can provide a more comprehensive and accurate assessment of a character's abilities and combat prowess in the realm of fiction.

## Rules Regarding Reaction Speed and Scaling

1. Reaction speed encompasses both a distance and a timeframe component, making it crucial to consider both aspects when calculating and evaluating reaction speed. It is incorrect to assume a fixed distance, such as 1 meter, for each timeframe and use that as a basis for determining reaction speed. Similarly, perception time alone cannot be used to derive a speed value.
2. When assessing reaction speed, it is essential to have specific feats or demonstrations that showcase the character's perception and response within a given timeframe and distance. These feats help establish a suitable reference point for calculating reaction speed.
3. In cases where only a timeframe is known, such as for characters who don't need to physically move to attack or defend, a perception speed rating can be assigned based on the timeframe provided. This rating reflects their ability to perceive and react within that specific timeframe.
4. If one character consistently outpaces another character in combat, it may indicate that their movement speed is scaled differently from the slower character's reaction speed. This scaling accounts for the difference in their respective abilities and ensures a balanced assessment.
5. When two characters are considered equals in combat, their reaction speeds can be scaled accordingly unless there are specific showings or discrepancies that suggest otherwise. It is important to evaluate the context, feats, and characteristics of the characters involved to determine a fair and accurate scaling of their reaction speeds.

It is crucial to note that any other scaling of reaction speed beyond these circumstances is subjective and should be discussed with the staff or relevant authorities for a proper assessment. Factors such as unique abilities, situational advantages, or specific story elements may influence reaction speed and require additional considerations.
