### 2.2 Why not show "PING value" on frontend display?
The most important reason for not showing "PING value" is simple: in most games the "PING value" is collected by a dedicated kernel thread which doesn't interfere the UI thread or the primary networking thread. As this demo primarily runs on browser by far, I don't have this capability easily.
Moreover, in practice I found that to spot sync anomalies, the following tools are much more useful than the "PING VALUE".
- Detection of [prediction mismatch on the frontend](https://github.com/genxium/DelayNoMore/blob/v0.9.19/frontend/assets/scripts/Map.js#L842).
- Detection of [type#1 forceConfirmation on the backend](https://github.com/genxium/DelayNoMore/blob/v0.9.19/battle_srv/models/room.go#L1246).
- Detection of [type#2 forceConfirmation on the backend](https://github.com/genxium/DelayNoMore/blob/v0.9.19/battle_srv/models/room.go#L1259).
