Yeah,

I tune both pianos to A440 and I don't compare anything. The 
musicians are making music together not comparing unison to 
unison.  I have never had a problem and have tuned duo pianos 
many times.  This is also how I was taught by Bob Erlandson back 
in 1973 at Western Iowa Tech.  The slight variations from piano 
to piano just adds to the color of the music.
