Thanks for asking this question! It looks as though both pages you linked to were pretty well transcribed.
Essentially, if you were to roughly preserve the layout of the page when there are accounts and numbers, it is helpful for reviewers. The same goes for the quasi-columnar text on the second page you linked to. If one were to transcribe that text in linear or sequential blocks rather than preserving the page layout, that would also be true to the instructions.
Hope this answer is helpful!

OK, so the underlines and such are NOT necessary (I've never figured out how to do them!). Thanks!
I agree with Lara. Those pages look good to me. Just make sure items make sense and researchers would be able to follow what she was saying. Underlining would be impossible and I have done it as was done in the pages you presented.
