Michael Gamble and I were restringing the 1867 Broadwood Cottage grand the other day and as I was watching his technique, it was apparent that often in manipulating the string into the kneb of the wrest pin it's possible to introduce a twist in the string. 

Of course when we come to tune instruments they're a long way from having been strung and anyone's memory as to whether the stringing method used had introduced a twist.

Upon mentioning the idea, we developed a better method of only putting the loop onto the hitchpin after having mounted the string on the wrest pin.

Has anyone considered the effects, if any, of a twist in strings?

Of course this might explain why false beats can be more prevalent in the top treble.

What type of wire? that could be some of it as far as false beats. How it is spooled makes a difference.

David-
See the articles by Ellis et als in the August and September 2008 Journals and the articles by Ron Nossaman in the April, May and June 2016 Journals.
These authors investigate commonly held beliefs about false beats, showing that most of them are false, and offer effective ways to reduce false beating.
Effectively, these are the beginnings of real understanding of false beats.
