I am not an EIT expert, but here is what I understand.

It contains information for its channel and maybe any other channels on
its multiplex. So 13_1, would also carry data for 13_2, and 13_3, but
not 5_1 or 5_2. That information would be on the 5_x multiplex.

That is what it contains, though right now I seem to get less accurate
data from it than what I get from DataDirect, but I think people are
still working on the best way to use it or something. This is
especially a problem on the upper multiplex channels of the local KET
station. It is almost always not correct.

Seems to be a choice right now. I know that the local 13 station just
started providing it.

I think the most recently received data seems to overwrite whatever was
there before, so I would think that would be what would happen. Plus
you typically only get a few future days EIT information.
Interestingly you picked two of the stations that I also have. Are you
in the Nashville TN/Bowling Green KY area?
