I'm not following your math.
1 of the 2 wonders "lost" also happens to be one the Harbs have completed.
That leaves 4 wonders for competition, 2 of which DoA will own shortly.
In the end we will see....it is going to be close.
It is basic. 7 wonders to build - 4 to own the board.
7 wonders minus 2 (lost) equals 5 open wonders. The two lost have been frozen out by HWC/Harbs jt ops.
Of those 5 open wonders...2 are going to Harbs and 2 look to be DoA.
That leaves 1 open wonder. 1 + 2 = 3.
The other two lost require you guys to go down:
A the rebuild option which leaves you behind others anyway.
B fight to retake cities and win the build on those wonders.
So do the math and work it out. All Harbs need to do is win 2 outright to make you guys have to fight in on min 1 wonder to remove the players stopping you from the build as it stands. You lose one more wonder island and then you need to fight into two and still hope they can't outbuild you.
If you notice I did earlier point to DoA getting 2 which I feel is easily in reach...but the other 2 needed are not which is the point here. It is not about the ones you are building now. It is about the ones you are not building now.
The send a stick to win the race is over.
