Thanks for that, but I’m afraid I haven’t yet had time. I provided the test code and target file in the hopes that others could confirm the scaling behavior and then experiment with algorithm tweaks, if anything obvious presented itself.

It does vaguely remind me of similar scaling with an old line-numbering algorithm, where lines were always being counted from the beginning of the buffer, so very fast at the front, and very slow near the end.
