better algorithm:
in previous version each next iteration looks in previous:
instead, 1st, 2nd, 3rd and 4th iterations all should look in the 0 iteration
so its more like original position
0
1
2
3
4
and then 5th in 4th, 6th in 4th …
as you can see in image above, with clock sequence, this estimator without Go logic may give too many points for black for example
So, I think better to choose direction that minimizes score difference instead of random
