These are hyper focused tests, only recording for a few seconds with the RPC executed in-between. In an environment with nothing else replicating outside the pawn itself and in an empty world.
I ran each test several times and had the same results. I haven’t tried it on Unreal 5 however but I don’t think much has changed on this front (could be wrong).
I’m just looking to further understand the WHY versus trying to fix it, while expanding on replication knowledge.
