It will no doubt be fun to do this for a bit - it’s great to have a plan to act on, with results you know you can measure.
That said, this will be much like trying to learn to drive by watching the GPS map screen in your car instead of looking out the window ahead.
The score-estimator is certainly not telling you where to place your stones, any more than the little arrow in the GPS map in your car is telling you which way to turn right now.
So it seems very likely that you will absorb as much about “how to play Go” by trying to use the score estimator as you would about leaning to drive by focussing on GPS.
I wonder if you have looked at the “Learn To Play” section recently?
It’s had lots of work done on it, and is pretty good.
If you can do all the stuff in there, that’d be great investment that actually would improve knowing where to play and why.
And if you can’t see the answer to any lesson in there, it’s something solid to ask about.
