[pianotech] Petrof Vertical piano string breakage

"If indeed it is a different string but the same gage as the one that
previously broke, I might suspect a run of bad wire from the factory.
Problem is, you have to wait and see if yet another wire of that size
pops". 
 
Paul, et al,
Why is it that no one suggests to check the darned String Scale??? (There
was one, (Ron N.), who alluded to it!) It is no big deal to calculate the
tension and breaking strength of the strings that are breaking!! Jeez
people, get with the program!!Join, (at least), the Twentieth Century!!
With all of the apps that are available and all you electronic junkies
flaunting all of your "new toys", that should be "child's play! Sheesh!
 The likelihood is there is problem with the placement of the
bridge(s)/Plate/whatever in those earlier Petfrofs. They were/are notorious
for their major screw ups! Sheesh!
