I am soooo grateful for this post. After years and years of words and one-off measurements, this is the first time I have seen clear measuring of the key metrics, specifically for someone considering the 'fast twitch shooter' (counterstrike et al) use case. To sum:

  - the satellite handoff period is 15 seconds
  - you cycle through the three nearest satellites
  - on the farthest one, inside the 15 second stable connection window, latency is 40 - 55ms
  - on the middle one latency is 30 - 45ms
  - on the closest one latency is 20 - 35ms
  - the moment of handoff between satellites is a 70 - 100ms latency spike
  - more importantly it is a near guaranteed moment of ~10% packet loss

so my takeaway here is "it will mostly seem fine but you will stutter-lag every 15 seconds". given that not every 15 seconds will be an active moment of 'twitch off' shooting the engine will probably smooth over most of them without you noticing.

this could probably be used in subtle ways the same as laghacking already is. like if you knew some packet loss was coming and you knew how your engine handled it you could do things like time jumps around corners so you appear to teleport. or if the engine is very conservative then you could at least know "don't push that corner right now, wait 2 seconds for the handoff, then go".

edit: side note, thinking about the zoom use case, and this would be kindof awful? imagine dropping a syllable every 15 seconds in a conversation.
