@ SLYSAM:
OK, now let's try to figure this one out. Yesterday is my "rest" day. SP credited me with 226 fitness minutes and 1150 burned calories. All of my fitness minutes were only FAIRLY ACTIVE minutes so if I divide the burned calories by the minutes I arrive at a figure of 5.09 calories per minute. When compared to the activities I performed on Saturday this data is hard to comprehend. I had over 81 minutes of very intense cardio work on this day (and 87 FAIRLY ACTIVE minutes) but it does not appear that I received full credit for it? If I use the 5.09 multiplier for my Saturday data I arrive at 855 burned calories (SP credited me with 736 burned calories) which is close. Now my curiosity is very high as to how SP arrives at their results.

Thanks Rockman, I also had a theory they might be using their own formula to estimate a calorie burn for minutes in each of the two levels Spark counts as exercise. I also use my fibit calorie burn, so it is more a curiosity. I do want my Spark and fitbit ranges in line though because the nutrition goals (vitamins, minerals, protein, etc.) are based on calorie allowance and I like to use the report to compare my stats to the guidelines periodically. It seems to work if I deduct a calorie per minute and make sure my other Spark and Fitbit settings match as well as they can.

@ SLYSAM:

I have noticed the same thing. Yesterday SP credited me with 168 minutes and 768 burned calories. The minutes equaled my FAIRLY ACTIVE and VERY ACTIVE minutes but the calories were off significantly. According to FB I burned 1,340 calories for those types of activity minutes. That is a difference of 572 calories!
SP must have their own formula for calculating the burned calories for the minutes that are synced from FB. And, they must be different values for either category because if I divide the total minutes with the total calories burned I arrive at an uneven number (4.57 calories per minute).
Nevertheless this is not an issue that negatively impacts me as I am receiving credit for the proper calories from FB (which is the site I use to guide me on my food choices) but it sure would be nice to understand why the large discrepancy and if there might be a way to "fix" it.

Just tired of beating something to death. thats all

Everybody tells me that they would love to knit, but they don't have time. I look at people's lives and I can see opportunity and time for knitting all over the place. The time spent riding the bus each day? That's a pair of socks over a month. Waiting in line? Mittens. Watching TV? Buckets of wasted time that could be an exquisite lace shawl. ~Stephanie Pearl-McPhee, At Knit's End: Meditations for Women Who Knit Too Much

"understand but even if you did not sync that day, when you eventually did sync it would be picked up and any information you manually put in would be alterned

the only way NOT to have anything eventually not sync over is to NOT wear it for those 24 hours that way information will not be picked up that you do not want to"

I am not sure I understand what you mean. I didn't log any activity that day, I just wore my fitbit. I didn't do any activity I would log--my only activity was walking. So there is no manual activity that would eventually sync. If I didn't wear the fitbit there would be no activity at all, so this test would make no sense as I was trying to figure out how Spark is getting the exercise calorie burn. It should be zero if I don't wear my fitbit all day. I don't want to not have anything sync over, I just want to understand what is being logged over here, as the calorie burn goal does effect our Spark food allowance.

Usmawife, I was just saying I didn't manually log any activity on fitbit that day. So everything is normal. When I do certain activities that the fitbit doesn't track well, I do log so in that case I would not be able to expect it to be clear when calories Spark is pulling from fitbit. I will say, when I log activity on fitbit, Spark definitely still pulls those minutes over if they fall into the right activity level. I thought my spark exercise calorie burn was weird because of manual logging, but on this day that wasn't a factor and I still could not see any connection between my fitbit calorie burn and the exercise calorie burn on Spark.

I was confused since you wore it and it synced over eventually if you then went and deleted the information

any activity or calories that is manually put in on fit bit site will not sync over which it true

guess that is what is confusing me with you wearing it and keeping that data alone since it will sync

Usmawife, I wore the fitbit all day but just left the fitbit data alone. Sometimes when I do exercise that fitbit doesn't track as well, I wear a heart rate monitor and log that activity on fitbit with the heart rate monitor calorie burn. I read in this group that the calories from activity logged on fitbit doesn't count here, so I thought that might be why I couldn't see where the number was coming from. Yesterday I didn't do this type of exercise, just some walking so I didn't need to log anything.

Just out of curiosity when you said you did not log any activity on the FB site, where you not wearing your FB so that it synced over

I am quite curious about how spark comes up with the exercise calories. I know the exercise minutes are for the minutes fitbit classes as either fairly active or very active. I assumed the exercise calories are just the total fitbit calorie burn for those minutes. But after looking at it in detail, I see it isn't the case.

I am using yesterday as an example as I did a fair amount of walking, but did not log any activity on the fitbit site. Here are the sources I am comparing:
*The fitbit dashboard--calorie burn, and the activity dashboard that shows the pie chart for the minutes in the four activity levels.
*The dashboard on my Digifit account. Digiffit is a heart rate monitor app that can link with fitbit, one of the views on the Digifit dashboard is the calorie burn from fitbit for time spend sleeping, sedentary, lightly active, fairly active and very active. These all add up to equal my fitbit burn that day so I think it is accurately pulling the data from fitbit.
*On Spark, the exercise log (exercise minutes and calories) and the "Calories Burned Differential Report" on the Spark phone app.

The minutes work out just as I expected. Spark counted 182 minutes, and that equals my fitbit fairly active + very active minutes. So far so good.

Now Spark credits me with 819 calories burned that day. When I add up the fairly active and very active calories burned (from Digifit, fitbit doesn't break this down), that results in 784 calories burned. So it must not be based on that.

I also noticed the calorie burn Spark assumes for me is higher than my total calorie burn on fitbit. According to the Calorie differential report in the Spark app, Spark estimates I burned 2447 calories. My fitbit calorie burn estimate for the same day was 2058. This difference... I think is largely differences in BMR estimates used. Spark uses Harris Benedict which always credits me with hundreds of calories more than other formulas. My fitbit bmr is similar to the Mifflin equation. At one point I noticed if I added my exercise minutes to the difference between mifflin and harris benedict bmr estimates that seemed to account for the higher Spark calorie burn.

The final thing that occurred to me, it could be a differential between my fitbit calorie burn and what Spark expects me to burn. Other sites that link to fitbit do this exact thing. Well, in the calorie burn differential report, spark assumes I burn 1685 calories. If I subtract that from the 2058 calories fitbit estimates I burned that day--the result is only 430 calories. So I guess it isn't that either?

Has anyone figured out what this is based on?
