[TowerTalk] Guy tension for Polygon guy rod?

[Scott Neader KA9FOX]

I am trying to check the tension on my 100ft tower, which uses 3/8" 
Polygon guy rod (guyed out at 100 ft).  There is 5/16" EHS for the 
last 15 feet or so.

I can easily use the Loos gauge to measure the tension, but I do not 
know what the correct tension should be for Polygon guy rod.  I 
believe I should be at 10% breaking strength, but I don't know what 
that is off-hand.  Probably this has been discussed before, but I 
can't find it.
