Third hit.

The edges will need one more final hit. You will be hitting them with the trowel mainly. The edging should be done. Hit any areas that look like they need it. The concrete surface will start to get very slick and the color will get darker slightly. Once you hit all the perimeter again, the edges are done at that point.

The interior hand hit will be the toughest yet. The concrete will be hardening up rapidly now. You will most likely not be able to sufficiently fill any holes and oopses, so be careful. You will need to put a lot of pressure on the trowel and it will also be raised up much higher than before. Both hands are needed at this point. If you use only one hand, you aren't doing anything to it and are wasting valuable time. Do the whole thing once more and that will just about do it for the hand hits. If any spots look fuzzy, yes it will actually look fuzzy, these will need to be hit again. Wait them out and finish up. Once all the slab looks and feels slick, that is it for the hand hits. You are no longer able to do any more to it by hand.

The third hit with the machine is much the same. Begin it when you are just about NOT leaving a footprint. This hit will slick the surface over even more and it will take on a fuzzy look. Some parts will start to shine a little and feel very smooth. That is what you are looking for at this point. Again, as before, travel 90° to the previous hit and overlap 6 inches. This time, go in close to the forms again. This will tie it all in slickness-wise and make it look more even. Do it all and then look at the shiny spots. They may be ready for the last final hit.
