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.

[IPC-600-6012] Legibility of Marking
Everyone,
Does section 2.8 Marking in IPC-A-600 apply to Legend (component
mark)? 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.
Thanks,
Wendi
