I went to like your post until I read the last line. I don't favour retracting punishments. On the very few occasions I thought I had over-punished my two kids, I was always mindful about reducing it against showing inconsistencies. If you really think you've gone over the top, at least see it through past the first party. Then if your daughter doesn't appear to be bothered, see it through to all three partie. If she's upset you can talk it through, reminding her why you considered her behaviour unacceptable, then offer an 'olive branch' for the next two parties.
