When I am fortunate enough to have a paper get accepted for publication, I often dread the final round of proofreading before I submit the LaTeX source files. Often, I read the paper start to finish multiple times and make incremental/superficial changes, but always have a difficult time calling it properly "proofread". In addition, I find this approach (multiple full proofreads) seems less useful for checking technical aspects of a paper (e.g., mathematical derivations or involved pseuedo-code) which is arguably more important.
I am wondering what types of routines people have developed for this situation. I would prefer to be much more systematic, as my current approach is both inefficient (time-wise) and doesn't seem very effective. Specifically, what do you do in order to call the paper "proofread" and feel comfortable sending it off to never be edited again?
