carlyngv, I looked close to all of your numbers. It seems to me like Bri needs more time on practicing separate hands. The time figure shows that she is in the process of developing fingers' awareness and eye-hand coordination. After the amount of time points will go down and will be less then amount of notes played, you may consider practicing the piano pieces with both hands.
Carlyn, on another hand, has very good numbers and it is time to hide the notes for her (press H after pressing R, L or P).
Just start video with the metronome - and ask her to play alone with the hands of the teacher on video. If she will follow the next step will be the second video with no metronome.
I also would suggest you to upload video footage of the children to You Tube and share the link with me. I would be able to understand the learning situation better, if I will be able to see at least hands of your children.
