I never read mine.
I use one boom for my entire quiver… so i have to read it to set things correctly.
I never read mine because things change depending on how much downhaul I use. On a bigger sail the difference can be more than one hole . I set the downhaul , pull lightly on outhaul with my fingers in the eyelet and set the distance with about 2 cm gap. It’s a vibe thing. Same with downhaul , I do visual cue on top crease, depending on wind. On one of my sails , which I marked with a texta needs 2 cm less on downhaul settings. I like to have about 2 cm gap between pulleys so I can play with my ratchet downhaul if the wind picks up. Some printed numbers can be out on sails. I had a NP sail that was 12 cm out. Not something you would expect from NP. Obviously a printing error. So I’ve learnt to rig by feel not numbers , that’s why I don’t read boom numbers.
