Would you care to comment on that?
I haven't heard that before but I'm not an engineer so I don't
know if that's true or not.
Changing the guy tension two-per-cent from 10 to 8% may not even
be relevant since most people don't take ambient temperature into account
when tensioning guys. There is a scale of tensions per temperature - I think
the figures stated for normal tension are for 70 degrees F or something
similar. Cold wx guy shrinkage and hot wx stretch make a difference. And it
might be tough to get accurate micro measurements anyway.
