MasterClient RTT for AI?

Options
I'm trying to understand the round trip time for seeing updates to AI if they are all controlled by the MasterClient.

Player A (MasterClient) host has a ping of 50, Player B has a ping of 150.

If AI is rotating and begins shooting at Player B and I am syncing rotation and isShooting bool, the AI clearly hits the player way before they see it and that makes sense. What I need to understand is what the full round trip time is.

Does each player have a latency to the relay and then again relay to player?

If Player A sends data to Player B, what I'm trying to get at is it's 200ms total time to get the info to Player B correct? This is different than if Player B had latency directly to the Host opposed to the relay and then to the MasterClient.
