What does the dB number next to the legend titles represent?

Where it says 82,2 and 68,3, is it just the average dB overall?

The figures are at the position of the graph cursor.

What do they represent? It's a single dB figure per entire line somehow.

Thanks for showing me. I noticed I can move it around at will, but haven't read up on what to use it for.

Does it change location on its own inbetween measurements? And if so, what does that represent.

In this and another measurement test, I did multiple measurements in a row, doing nothing else than clicking on/off the record and save buttons, and they all had different dB figures.

That's the graph cursor. It goes wherever you click the mouse on the graph and the legend then shows you the values of the graph traces at that cursor position, which for most graphs is a frequency.
