I lost 2.8 pounds again! I did get 3 readings from 3 places in the room (the floor is wobbly). I chose the reading that was the most level (in the middle of the room). There was a lower number but I could rock the scale a little and I didn't think it would be fair and I'd pay for it next week.
So, hurray-hurray. I also have the lowest weight I've ever recorded on MyFitnessPal. I had a short run of entries in 2013 that were skirting around this weight.
