I used MMW again this morning. It says 5.0 miles in 80 minutes, 3.8 mph, 9771 steps for 571 calories. It does track elevation change, which was significant at 212'.

My watch got other activity as well; walking around the house and whatnot, but I am not sure that accounts for the difference. It says 10340 steps, 4.56 miles, 476 calories in 108 minutes.

mfp got the full 571 calories logged from MMW. I wonder if yesterday it adjusted because I had already logged some walking.

I am torn about whether to leave the automatic logging on or not. I could end up adjusting my base lower and then not eating enough when I don't exercise. OTOH, it could be accurate. I thought I was walking slower than 3.8, but I feel sure MMW gets that right. It was hilly, so I guess throwing 20 flights of stairs into the equation (or 10; I think that means 100' down and 100' up since I started and ended at the same place) makes the high number a little more believable.

Another weigh in tomorrow, so I will see if it budges any.
