fussiness and small fonts have forced many of our builds to photoimageable legend instead of stencils. i agree with your interpretation that as long as you can figure out a letter or number, it meets the requirement for legibility.

We are increasingly seeing designs with very small legend features causing discussions at final inspection as to whether they meet the requirement for legibility. From what I understand legible means at no more than 2x you can understand what the symbols are. Fussiness and filled in holes in letters are allowed if you can tell what the letter is. Would appreciate some guidance on this.
