Tuning an in mast furling rig

Fellow 310 owners.
I'm sorry to bring this topic up again but I lost my numbers for tuning my rig that has in mast furling. I have my mast nice and vertical. I have the new Loos gauge.
Some sailers say they like to tune to 15% of breaking strength but not me. I thought I had my uppers at 1250 and my lowers (fore and aft) at 900 but not sure.
Anyone have their readings that work for them for in-mast main furling.
Thanks again.

With a masthead rig with in-line spreaders, what is your aversion to tuning to an industry standard number for shroud tension? Its best in that range. Your mast will not bend under tension due to the straight spreaders.
