I do get frustrated by fitbit's accuracy, particularly the flights counter. I know that there is some variability in tracking steps using an altimeter. However, my versa 2 is incredibly erratic. I live at the bottom of a valley and have the opportunity to walk up a pretty steep hillside. From my house to a frequent turn around point is about a 900 foot climb. My versa 2 has recorded this climb as everywhere from 2 to 100 flights. I really don't mind too much about errors like + or - 10 flights, but 88 flight errors shake one's confidence in all measurements. There are days when it seems OK and then there are others, like today, when I really feel the frustration.
