Comment (by simonpj):

 That sounds very plausible -- thank you!  Do de-clutter when you are done
 :-).

 In fact if you grep for `seq` you'll find a variety of `seqs`, some of
 which probably do nothing useful while costing execution time.  You are in
 an excellent position to find out, if you feel up to doing so.  Really
 each should be accompanied with a story for why it is there.
