Avatar networking issue 1.14

Is it possible to get updated documentation about packet recording and
playback ? i used to dismantle the packet to optimise size of what goes
trough my network

OvrAvatarPacket packet = args.Packet;
            OvrAvatarDriver.PoseFrame frame = packet.FinalFrame;
     
        using (MemoryStream newoutput = new MemoryStream())
        {
            BinaryWriter writerb = new BinaryWriter(newoutput);
            writerb.Write(new TransportFrame(frame));
            byte[] pose = newoutput.ToArray();
            latestposition = pose;
        }

TransportFrame in this example being a heavily lightweight class and i was doing position lerping on clients.
Is there a way i can still do this using the current system ? For example can i still retrieve the FinalFrame in any way possible and use it for avatar update on client side ?
the system in 1.14 makes my bandwidth usage go up 2000 % for pose updates (1Kb per pose instead of 50 bytes) :/

Thanks for any feedback.
