This will insure a tight joint between the tread and the riser. While speed is of the most importance to stair professionals, it is your worse enemy. Think about everything you are doing and take your time. When I'm working, my mind is always one and two things ahead of what I'm doing, and it is important to be thinking about how things will effect things down the road. You should not be worried about speed. Someone should always be here to answer any questions that come up. Good luck.
Yes that sistering looks fine.
