The obvious complaint about a repetitive PDF is that it's tedious. Twelve blanks, one name, twelve times typing the same eleven characters. That's real, but it's not the expensive part.
The expensive part is what happens on the ninth occurrence, when your hand is on autopilot and you type "Jon" instead of "John." Or the eleventh, where you abbreviate the street name because you're tired of typing "Boulevard." Now the document has two versions of the same fact living inside it, and neither version is wrong exactly. A human reading either one would understand who's being referred to, but they don't match, and somewhere down the line, someone whose job is to check for exactly that kind of mismatch is going to find it.
Retyping the same fact repeatedly is slow, and it has no built-in way to catch its own errors. Every occurrence is an independent chance to introduce a small variation, and nothing about typing the elevenths blank tells you it doesn't match the third one. You'd have to go back and compare all twelve by hand to know for sure, which almost nobody does, because by that point you're just glad to be done.
This is why a misspelled name or an inconsistent address shows up so often in exactly this kind of document. Not because people are careless, but because the format of "fill the same fact in twelve separate places, one at a time" has no mechanism for consistency built into it at all.
It's typing the fact once, in one place, and letting that single entry populate every occurrence. Not copy-pasting twelve times (which still requires finding all twelve spots and still allows one to get missed). Treating the twelve occurrences as one underlying fact with twelve places it needs to appear.
That reframing is the entire idea behind PDFeyes: find every place a fact repeats first, then let you fill it exactly once. It's a small shift in how the problem is framed, but it removes the specific failure mode. Quiet, hard-to-catch inconsistency, that repetitive retyping creates almost by design.
Type each answer once, place it everywhere it is asked for.
