I do at least 10 floors per day. At times, I'll complete a floor and the watch won't count it. But today, I completed 3 floors and as I finished my fourth the watch recorded it as 99. I did one more floor to break 100. Ha. Actually, I'd prefer not having that in my record books.......but there's no way (that I know of) to delete an individual tally such as this.
I hope this isn't a sign of more bad things to come.
