Laser worked best for me YMMV
I finally used a laser into phase I, and found the holes don't all exactly line up (along the full cord). Logic was to use the most extreme spread, but ended up splitting the differences. Like an eyeballed least squares fit.
Conclusion: precision is to be welcomed but not expected.
After checking everything, I slotted the hinges, adjusted a few times and balanced my "heavy wing"
