What happens if you string above the recommendation?

So my racquet is 55-62 pounds but what if I string it at 65 or even 70 pounds. Will that hurt my racquet or strings in anyway? Whats the worst case senario and what should I expect to happen?

As far as what to expect:
You will get a stiffer stringbed stiffness.

Todays racquets can take a lot more abuse than the old ones of years ago.
Stringers on the GSS site a while back commented on Seles Yonex frames strung in the mid 80 lb range and also other tour players with extreme high tension. What that shows us is that these racquets can take quite a bit of punishment.
I assume that most string according to manuf. range to keep warranty issues and safety
of the racquet and stringer. If someone asked me to string one up in 80's, I would get a signature of consent that damage may occur just in case, and would wear safety glasses while stringing.
