winning condition achieved, game didn't end

[gggol]

I'm in a 2 player game that has "Winning condition: Capture 80% of standing cities"

This turn I captured 4 more cities and exceeded 80%, reaching "My city percentage: 86.5%". Shouldn't I have been declared the winner as soon as I exceeded 80%? Or, if I am over 80% at the beginning of a turn, shoudn't that trigger it? My opponent went first.

You need to have 80% of cities or more at the start of your turn. So your oponent has a chance to stop you still...
