Strings permanently elongating just before breaking isn't 
news. It's always been acknowledged.

It's a meaningless question, put that way. If a string is at 
30% of breaking tension, you can very likely pull it 200 cents 
sharp without a problem. If it's already at 70%, you most 
probably can't. Treble tensions tend to be at a higher break%.

Probably not enough to immediately induce false beating if the 
cap is new.
