For example if it does underestimate cycling then cycling 2h one day will show up as a much bigger error than on a day when you did nothing. |
It is more elaborate than "just" a formula. It has a 3axis accelerometer, it measures your heartrate and body temp, and other things. So… it's taking in a lot of variables to make its formula it uses… based on those factors (way more than just your height, weight, age, and sex), and spits out something that's been pretty close to accurate for most of the people on the board who have it.
Now some people find the HB formula and whatnot perfectly working fine, are losing just fine, and don't have a reason to bother (like me) because what they're doing is working so they can spend their money on something else. For others, they have issues and get it and find they burn significantly more/less than they thought and it's helped set them on the road of loss because of that. Some people also find it a motivational tool… in part because it'll give you a number to shoot for, in part because they spent the money they might as well use it.
It's a lot like a gym membership or even owning fitness equipment at home… you can do the job perfectly well without it… and people have for a very long time… but for some it's a neat tool in their arsenal and works great for them. Other people don't think a gym membership is worth it for $30/month when they can take walks for free, do pushups for free, and buy a $30 bar for pullups (spent only once).
I believe it'd be a great tool for me if I got it… but like a gym membership at the moment… I just don't want to spend that level of cashola when I'm seeing results without it. *shrug* yvmv
