To briefly summarize, the modified script found a small number of matches that the original script didn't, occasionally the line number was different (almost always by 1, but a few times more), and the tolerance returned by this test version was also <= the tolerance returned by the current version. Admittedly, with the other two directions added in, a more extensive test (a total of a bit under 14 minutes CPU time on a Ryzen 4700U) showed the new version is about 0.5% slower, so there is a very minor downside. (I'd happily spend the extra matches for the minuscule amount of CPU time, but others may not.) Cheers.

If nothing else, it will keep other people from asking the same question in the future. :-) > so those 14 minutes, was that N times a file or 1 time a huge file? N times a file: I swiped the code from the program and defined two functions, one (test_old) one for the current code and one for the new code: test_new () { for x in $=x_vals do for y in $=y_vals do printf "%3d, %3d: " $x $y out=`mtxrun --script mtx-synctex-jd.lua --goto --direct \ --page=$page --x=$x --y=$y --tolerance=$tolerance $st_file` echo $out done done } (The test_old was the same except for the argument to --script, which is 'synctext'.) I defined $page=15, $tolerance=300 and $st_file to be a file with 3441 lines (there are 19 pages in total, so I was skipping a lot of stuff) and changed x_vals and y_vals to create a lot of iterations: x_vals=`seq 100 5 550` y_vals=`seq 100 5 700` and finally I ran time (test_new > /dev/null) and time (test_old > /dev/null) So mtxrun was called for each of these 11,011 times. Not the best possible benchmark, but probably good enough to show that adding the other two cases isn't hurtful. Cheers.
