I see. I thought there might a simple turn-off for anything not step based. No real problem, I have a spreadsheet that I think is reasonably good where I assign calorie burn rate to floors and steps based on whatever I can learn about data on these things. Then I just add C2 calories, which I believe are quite accurate.
On days that I do house cleaning, vacuuming, scrubbing, etc., I think it may underestimate, since all I get is steps. But no big deal.
I believe by far the fastest way for most of us to use calories is running. I never really liked running, so I used games. Now, I am not supposed to run. My surgeon said I could play tennis or squash, but some joint replacers feel very differently. I know walking is safe, and so is rowing. So these will likely be my mainstays. I don't really like most gym machines; it's very different from being out in the world. Even when I row at home, I have my big windows to look out, or sometimes a movie on TV so that is somewhat boring but not too bad.
Thanks for the pointers.
