I typically do a 3:1  D3(3)--A4(1)  tested with a F2(5) and then set 
A3(2) to a position slightly narrow of D3(3) and slightly wide of 
A4(1).  I find it very easy to set D3(3) to an A440 fork using the 6th 
below test as an aid. Then setting A4(1) to that same is a snap. Which 
yeilds me an A4(1) at 440.

As long as I am on about the Maj6th test for a P 12th... I might add 
that for ear tuners that is a really quick way of running through the 
treble... even if you are primarilly an octave types tuner.  You will 
find that quickly seting the 18th and the 6th to the same beat rate all 
the way up to C8 will allow you to simply tweak your octave to taste on 
your second pass.

Personally.. I tweek now so that when running chromatics 12ths, 20ths, 
triple, double and single octaves.. there is no single beat rate that 
stands out as being slower or much faster then the previous one.  
Typically I find a strong tendancyt to let the 12th go very slightly 
narrow at about G7.  I end up most of the time with C8 at about 28-32 
cents +-
