Greetings, 
    Yes,  there are ways.  They are called SAT,RCT, VT etc.  (Pitch raisins 
don't mean throwing dried grapes around).    
      This morning I was called to the "Mother house", a Catholic home for 
elderly nuns here in Nashville.  The Steinway B had been left flat some years 
before and I was looking at a pitch raise of 10 cents in the bass, 15 cents 
in the middle, and almost 40 cents in the 7th octave.  
    I used the SAT to give me a compensated measure at each octave as I went 
up from A1.  After 15 minutes, I reached C88 with the entire piano at 440, 
give or take 2-3 cents.  That is really close for this amount of raising.  
Then, I spent an hour tuning a Moore and Co. Victorian style ET,(which is 
really a mild WT).   Sister Rosemary loved it, said that is somehow sounded 
like the piano she remembered from her youth, and she is not old enough to 
have been around in 1880. 
  How close is close enough?
