Thanks for the clarification. For the record, it went like this:
- OK, git then grep, obviously.
- Bleh. Do I have to put together some awk or perl to collapse and count 
the lines with identical delays? I dunwanna, but if I gotta, I gotta.
- Wait, doesn't uniq have an option for counting duplicates? *checks 
uniq(1)*
- Sweeeeeet, it does. So sort to get the lines with the same delay 
together, then uniq -c
- Hmm. Sadly but predictably, there are variations on the MFC format, 
but a sed stage can help with that. (That one went through 3 or 4 
revisions as I experimented, I think.)
- So far so good. Now how do I get them in the right order? *digs 
through sort(1)*
- Hmm, -k 1nr is all it takes? Could be much, much worse. I'm looking at 
you, DFSORT and IRRCO00.
- Do I want to make sed handle more variants? Naaah, diminishing 
returns. That's a wrap.

Total time was 20-25 minutes IIRC. Not that long considering, but still 
nowhere near "dashed off without a moment's hesitation" :-)
