[UDP] stage_current_distance increases when driving to the opposite direction.

Hi there, as read from the UDP Telemetry Guide v1.3:

The title sends packets at specific times over the lifetime of a packet “scope”

and there're scopes like "session_start", "session_end", "session_pause", "session_resume" and "session_update". I tried them and found only they differed on ip/ports, channels inside, frequency etc. but the packets I recieved are during the whole lifetime of the session, not "specific times". 

for example, "session_start" send me packets from the beginning when the car is on the track, and to the end when the car pass the finish line. there's no difference with "session_update" scope. From what I understand, the "session_start" should only send packets when the session begins?, and "session_end" only send packets when session ends?

It is really confusing.. and from "session_update", I cannot tell difference from the packet's data on when the track session paused or ended. since the UDP data behaves the same (data stopped recieved when paused and session end).

Thanks.
