In networking, ping commonly refers to the time required for a packet to travel to a remote host and for a reply to return. The number depends on distance, routing, network congestion, Wi-Fi quality and server location.
That is a network property, not a biological one.
A reaction test can generate the go signal and timestamp your click inside the browser. Both events occur on your local device, so the core timing does not require a round trip to Reaction Lab’s server.
Analytics or leaderboard submissions can happen separately after the local result has already been measured.
Multiplayer games need to exchange state with a server. Your input may be processed locally for responsiveness, but authoritative hit registration, other players’ positions and server reconciliation involve the network.
Game-specific networking techniques such as prediction and lag compensation can change how latency is experienced.
If a Reaction Lab result says 210 ms and your game ping says 30 ms, subtracting 30 to claim a “true” reaction of 180 ms is not valid. The two measurements are not stacked that way in a local reaction task.
A poorly designed test could start or stop timing based on a server response, in which case network delay would contaminate the measurement. Reaction Lab’s gameplay timers are designed to run in the browser so the reaction interval itself is local.
No. The core reaction timer runs locally in the browser rather than waiting for a remote server response.
Yes, network latency can affect when remote game state reaches the server/client and how interactions are reconciled.
No. Ping and the local reaction measurement are different timing paths.
