Poorly. The signal strength in the locomotives simply measures how many good packets vs bad packets it gets for a test stream. Depending on the circumstances, it could be getting all good with low voltage from the TIU. Also, as we all know, a good TIU with bad wiring/track layout will yield bad results.
This is a tool to test the TIU independently.
Actually, since we’ve been talking about lengths.... the MTH signal test also uses a very short test packet like the length of a speed command (about 500us), so it’s skewed to be very optimistic and doesn’t inform the situation for longer commands like adding engines or app reads

I think I knew this before I asked?

Again, thank you for the time to explain things.
