I wonder if your premise is really true.  The core supporters of Greek or Anti-Greek
will certainly prefer you to the other side.  But many voters may vote for one of these
two sides without viewing everything in the Greek vs. Anti-Greek dichotomy.

However, I am going to assume your premise for analysis.  I have also conjectured an
even split in the second preference for the people who vote for you first.

164 A I G
52  I A G
52  I G A
83  G I A

A 380
I 455
G 218

	A	G	I
A	X	216	164
G	135	X	83
I	187	268	X

This means the pair-wise majorities, with margins are:
A>G 81
I>A 23
I>G 185
So, there is no contradiction, "I" wins.  The second preferences of
the I 1st voters don't actually matter as the "A" vs. "G" votes don't 

You also win under AV.  However, the Anti-Greeks could claim that
they would have won if they had less support.  If 22 people decided 
to vote "G A I" instead of "A I G", then "A" would win under AV.
You would still be the CW, however.

I tend to view the CW as giving the best government.  It certainly
seems likely that the Anti-Greek candidate will support Anti-Greek 
measures that are far more extreme than would be desired by the 
majority of the electorate of your district.
