Building off of yesterday, in the morning today, I asked for 3 perfect G scales from M and 1 perfect G scale with knocks. It took about 15 minutes, but she was generally cooperative and successful.
In the evening, I asked for 2 perfect G scales from M and 2 perfect G scales with knocks. We never did get the perfect G scale with knocks, so I gave up and substituted another ordinary G scale. M did more fidgety crap than I would like, but it was basically conflict-free.
I’d count today a success.
