Ok, be honest

If you have serious reason to believe that your weight is either artificially high, or low, do you still record it if it's a weigh-in day? Case in point: I had a huge dinner at a Brazilian steakhouse last night. I bet it was the largest meal I have consumed in 2015. The scale was up roughly 2.5 lb this morning compared to yesterday morning. Monday is typically the day I update my weight in MFP- I just couldn't bring myself in input that ugly number, especially since I feel like it will be back to "normal" tomorrow. Similarly, if the number had been artificially low (i.e. if I'd slept in really late after having an early supper the night before), I would not be inclined to record that weight, either. How does everyone else handle this?
