Yes, for practical purposes it's a fair rule of thumb but in fact the 
more the wire is drawn the greater its tensile strength for a given 
cross section, so that a thinner wire will reach a _slightly_ smaller 
percentage of its breaking strength for a given pitch and speaking 
length.  The amount involved is hardly likely to solve any practical 
problem.
