Can't edit my post - posted too soon. 20 min -> 17 min was unnecessary for the client, but... 2 other people got to 'share' in the credit, because 'the team' got this down from 25 hours to 17 minutes. They got to learn something, after telling me it was 'impossible', but... that wasn't enough. They needed to put their fingerprints on it, then got to take credit for something. And took it they did. Annoying as hell, 15+ years later.
