Primes¶
- Access Catchment
- The 5-minute walk, the 8-minute ambulance-response target, the 100-millisecond latency tolerance — each is a chosen number that defines the catchment, and changing it redefines who is served and who is not.
This sourceEstablishes 0.1 second (~100 ms) as the limit below which a system feels instantaneous — the canonical basis for the ~100 ms latency tolerance used as a chosen catchment horizon in interactive/CDN systems.
Supported in partVerified against the work's full text
Nielsen supports 0.1 s as the perceptual limit for an instantaneous-feeling response; he does not discuss catchments, walking times, ambulance targets, or who is served.
“0.1 second is about the limit for having the user feel that the system is reacting instantaneously”

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
