T6c and manager show different Kcal

[Vkohli]

Hello all:

I have been trying to figure out why the Kcal on the T6c gives a higher value then training manager. For instance, on the watch it indicates I have burned 535 Kcal, yet training manager and firstbeat show 202 Kcal. I made sure that both the training manager and watch have the same personal settings (i.e. weight, height, max HR, METs, activity class etc.). Yet, I still get different values. Am I missing something?

In addition, for some reason when I sync the watch with training manager a box shows up saying that the parameters between training manager and the watch are different. Looking at the numbers for both the training manager and watch show that they are identical. In one instance, for some reason after syncing my T6c with training manager, the software tells me that training manager has my height set to 172 cm and the watch set to 171 cm. I immediately check my watch and it is not set to 171 but to 172 cm, making it identical. This is just strange!

I am using the latest training manager software provided on Suunto's website.

Aside from differing Kcal, every other parameter agrees between the watch and training manager and firstbeat.

Any help you can provide would be great.

I too see a difference between estimated kcals betwwen what's logged on the watch, and what shows up in the software.

I believe this is because depending on the version of the software, the model used to estimate kcals is different. One would presume suunto is refining the accuracy in the software model.

Training Effect and EPOC peak also differ. I would expect yours to as well, despite your claim that kcals is the only differing value. I just checked; even some of the HR data is slightly different!

That said all my observed differences are small; the kcal difference is MUCH less than yours. Perhaps you are comparing two different log entries?

deedubya,

Thanks for your reply. Having all of the parameters set correctly in both FB and training manager, the Kcal values between the watch and softwares are consistently off by about 50%. Yes, the EPOC and TE do sometimes differ, however, the differences I usually see are between FB and training manager. Comparing the EPOC and TE of the watch with training manager, they are usually identical (i.e. TE of 4.1 vs 4.2). As previously mentioned, I always check the % error in FB to see how the heart was recorded. I normally get an error percentage < 3%.

As for comparing two different logs. I made sure I was looking at the same log file, so that can be ruled out. I even went a step further and exchanged the watch for a new one. The new watch that I used yesterday gave 545 Kcal vs. 249 Kcal on both FB and training manager. % error was 2%.

In regards to software, I am using the latest version provided on Suunto's website.

This large variation I am seeing is not right. If this is expected, then I see no point why Suunto should have included it as a display option on the watch.

New watch and same problem to me indicates an algorithm problem in real-time Kcal calculations in the watch.

I spoke to Suunto and they even said the percentage error I am getting is too large.

Still trying to determine if I am missing something in all this Kcal business.

Vkohli,

you may need to look into your VO2max on both the watch and the software. It seems that the calories estimate is off if the VO2max is set either too high or too low for where you really are. I had Eddie Fletcher on the Suunto Discussions look at my logs and help me determine my VO2max from few runs and race results. Basically the recommendation is in live with VDOT tables from Daniels. After setting my VO2max to that value and setting my activity level according to my weekly training hours I see much closer calories burned between the watch and FB athlete/STrM.

Vkohli,

Did you ever get to the bottom of the kcal issue? I am seeing a large difference in kcal between the watch and software, as well as TE and EPOC differences...

Wondering if you ever got it sorted..

[Carceri]

I am seeing an about 30% difference in kcal values between TM and my t6c.

likewise seeing differences and the other values on the watch/manager are identical.

What's odd is that sometimes the values on the software are lower than the watch, but more often than not they're higher.

the values on the watch generally seem more in line with my expectations for a given workout.

does anyone from suunto actually monitor this forum?

best

I just got a 69% error reading from my memory belt (and T6C watch) when I downloaded and analyzed in FirstBeat ATHLETE software. I ran rather hard this morning (Fartlek).

Interestingly, my watch this morning read a TE of 3.4 and EPOC of 81 (on review from watch after run). The FirstBeat software showed 2.7 TE and 43 EPOC. I also downloaded the watch and belt to Suunto Training Manager, and got a third set of results (TE 3.0 EPOC 52). My watch and both software programs have the same profile info (e.g. METs, Max HR, etc).

BTW...on reviewing the individual data points in the Suunto software, I seem to have all of the data (nothing missing...10 sec intervals for 35min). However the FirstBeat software shows large missing data sections after the first 10 min. The data is very consistent for the first 10 min, then it looks like I lost 90% of the data for the last 25 min.

Why would the data show in one software package but not another? Why would the three devices show different TE / EPOC even though the personal data is the same? What gives???

I personally would go for the Garmin - an all in 1 unit (excluding Heart rate monitor) rather than the Suunto which is multiple units.
