Hello Thomas, hello Robert,

I see what yoou mean. My situation is, however, somewhat special.
(1) I am not a programmer.
(2) I want to use commercialy available go bots in human+computer teams. 

So, I want to learn how to read the information these bots
give during their analysis. And one of the (more detailed)
questions was/is, how to read upcoming Seki (and how often
Seki occurs at all).  Of course, I am aware that Seki is one
of the possible outcomes of a semeai.

Look into the following diagrams. They are from the Aya-vs-Zen
game on 13x13 from the KGS bot tournament in August 2015.

Knowing the outcome of the game, it is rather straightforward
to interpret the histograms. What I need (in the future) is to
understand the development of the fight during the running game. 

Thanks again for making the whole complex more clear for me.

Cheers, Ingo.
