Wow, I've seen a lot of improvement in the past week. Not so much with the Bubbles game, but with the Brock String. I'm not sure there are enough data to identify progress in the Bubbles scores. You might see a very slight incline if you try to draw a straight line. The 18th was just a crazy day. For some reason I just kept making the right guesses again and again, staying in the higher levels.
I just completed my exercises for the day and am finding that I'm consistently better at the Brock String. It's almost easy now. My control isn't perfect, but it sure feels like it's getting there. I get the X every time from bead to bead. A few weeks ago I would get tired after 20-30 seconds. Now I don't get tired at all--even after 10 minutes.
Dr. Tran suggested that I do jumps from up close to distance while standing up. He also suggests that I do the Brock String such that I am looking upward at the string and beads. So I had to move the Brock String and tie it to some cabinets so I could look up at it while standing. That's what I've been practicing. Close, distance, close, distance. I've also been taking care to look through my acrylic target contraption. I suspect that is exercising my binocular neurons so they get close-up stereo cues (drawn-in concentric circles) while I'm looking in the distant beads.
I'm going to have to figure out some ways to load the exercise to make it more challenging. I'll probably ask Doctor Tran soon. I do expect the Bubbles scores to increase very dramatically in the coming months.
