False beats

Yes indeed, I have detected false beats becoming apparent when pitch
raising, mind you quite severe pitch raises - 200 cents. The likely cause is
the kinks in the string (formed after years of being in contact with the
bridge pins) being pulled through to the speaking length. The kinks take
quite a while to straighten out but I have found that an immediate pitch
raise to concert pitch is more beneficial than a few false beats here and
there.
