No, they are not researched. When the ply number has a ':' after it, it means I have completed an iteration and the best I found is the following. In other words, it is a summary. If the engine did not change its mind, you will see

1370512 8 4.7 +0.28 1.f5 Ne5 2.Qf4 Bc8 3.Bxf6 gxf6 4.fxe6
fxe6 5.Qxf6

(Engine thinks f5 is the PV move and the score is +0.28 after searching 8 plies)

1592012 8: 5.5 +0.28 1.f5 Ne5 2.Qf4 Bc8 3.Bxf6 gxf6 4.fxe6
fxe6 5.Qxf6

(Engine is saying: I searched all moves and the best I found is f5. This is what I think is best so far, which of course has the same PV as previous one since I did not change my mind)

Now that I read my post I think that I blew the 8 out of proportion :-)
