The best method I have found so far to determine the 20% tension point is using the folding rule method described in the Selden mast book, attaching a 2 meter stick to the stay using tape and measuring the distance between the stay end and the stick. When the wire has stretched 1mm (the slack distance has increased ) that would equal 5% of breaking strength.
Sailing Dog, I like Alex's videos alot. They do give a good idea of what to do and why.
Yup...you got it in one.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
