Selden Mast Tuning manual (http://www.seldenmast.com/files/1416926327/595-540-E.pdf (p.31)) says that the shrouds should be set to 15%-20% of the breaking load. Keep in mind that you have at least 4 shrouds plus the stay and the backstay. The letter two are at less acute angle, so the force is reduced (by the cosine of the angle (the force is reduced for the shrouds, as well, but the reduction is around 2%, so who cares)).

I'd think 50% of that would be conservative. Dennis C.
