Yes, this is one of GNU Go's main weaknesses.

Spending more time here would be perfectly okay, if we just can find
something useful to spend it on. :-)

I'm unsure to what extent the weakness calculations can be expected to
be useful in early and open positions like this, maybe Arend can
comment. Otherwise potentially useful information includes surrounding
moyo size, territorial value of the surrounding moyo, escape
potential, and surroundedness data.
