Well that worked out well...
I don't think you have much of a case here. I can't speak authoritatively on the fine-tuning of airport scales, but I'll make the educated guess that they are more accurate that the $20 bathroom scale in a hotel.
The bigger point is, where do you draw the line? Sure, 1lb isn't going to kill anyone but what about the person who shows up with 3lbs over the limit? Or 4.2lbs? You need to have a rule that all can clearly see. If the agent is flexible, great for you. If not, well, you shouldn't expect it. We had the same discussion elsewhere regarding miles/PQD for requalification.
