Blind Pitch Raises

[mps at usol.com]

It is a mystery to me how some of us techs can do a blind PR without 
mutes (and in just several minutes). It is quite apparent when raising 
one string of a 3 string unison, the other two will sound in addition to 
the one being raised. This can confuse me and I am usually off when I 
end this technique. I end up doing almost two full tunings because I 
can't seem to get this down with any speed.
Does anyone have suggestions to assist in this problem?
I've been running into quite a few 100-120 cents flat pianos as of late 
and as you know, time is money.

Thank you 
Mark
