Confused about how "estimate score" works

[Lys]

Recently I discovered that score estimator may be wrong.
Here is a topic where I discussed my doubts:

Score estimator: what it's for?

I’ve been using a lot score estimator provided by OGS until few days ago. I know it’s a bad habit, but in my roadmap to improve the counting skill was less urgent than other topics. Lately I won a game by resignation. The opponent said “I think I am too much behind” but the score estimator indicated he was ahead of about 10 points! This situation was eye-opener for me: I suddenly discovered that not only the estimator was wrong but also that it’s unreliable and inconsistent. If you keep click…

Look at the pictures I posted in it.

The fact is that on the roadmap to be a full go player, counting score is very important. Maybe not urgent at first, but very important indeed.

Now I try to count as frequently as possible to train myself and get a quite good counting in a short time.
