Don't know, but going from a Young to ET will only cause the A's to move 
about .3 cents. This is well within the daily rise and fall of pitch any 
piano goes through daily in the home, so I don't see there being any problem. 
 In my practise of yanking pianos out of ET every chance I get,  I haven't 
had a pitch change problem yet.  
   After doing the Meantone tuning on "6 Degrees",  I had to put the piano 
back in ET for a student recital before we restrung it.  The A's stayed the 
same!
