Why isn't total elevation equals to the sum of the all values in day?

[moscoquera]

im trying to find a bug i hve with my data and Fitbit's support keeps "thinking"/trying to tell me how the altimeter works . my problem is about the way fitbit logs the information becuase the "driving" activity ins't negating those extra floors from the total. so im just checking the api to see what can i figure out.  at this moment all what could "discover" is that exists a huge diference between the "total" value and the detailed data. but i dont know why.

example: https://paste.debian.net/905733/

if i do a sum of all the "value" fields im getting just 12.192000389099121, and the total elevation of the day is 103. why are those values so diferent?

this is intended to be in the developer forum, can someone move it there? pls?

Intraday values may not always sum to their daily value. Fitbit devices will purge intraday values in order to preserve daily values in a variety of circumstances, such as when device memory is constrained and when battery level is very low.

Hi.

isn't that a problem when users use the"driving" acitivity to negate steps? i mean, if all the data isn't avaible how does fitbit the "exact" amount of data to negate?. I'm asking this because i still having a problem negating a lot of extra floors fitbit record and adds to the total but no to the intraday data. I'm going to do a reset and see if this solves the problem.
