Reliability of web socket subscription

[LeoPatOZ]

I've come across multiple sources mentioning that WebSocket subscriptions may not be fully reliable for tracking blocks and events (i.e., occasional missed blocks/events).

However, I'm having difficulty finding concrete data on this. Are there any statistics that quantify the reliability of WebSocket block subscriptions? Specifically, I'm interested in understanding the typical percentage of missed blocks or any metrics around WebSocket reliability for real-time block monitoring (also in the context of missing a reorged block).

Any insights or references to relevant documentation would be appreciated.
