What is the meaning of the number in parentheses in the info box (at the end of position accuracy line)

[smbatpetrosyan]

As far as I understand the help document https://alpinequest.net/en/help/v2/geolocation it's defined as fix number.

The current location accuracy, its elevation, speed, and fix number;

But it's unclear what does that fix number exactly mean.

Hi,
When a new location is computed by your GPS chip, this number is increased.
So for each new location, this number changes.

So on a long train trip, it should get into the thousands?

And when does it reset to 0? When we e.g., switch to Gmail and then switch back?

Or when we turn off the location slider to no longer track our position?

It does help to know quickly if the GPS location is updated correctly. When the number is stuck, you know that the GPS struggles.
jidanni, it's quite easy to check when it does reset. But this number only concerns on map-real time location, it's not related to the track recorder.

Seems that "seconds elapsed since last fix" would be more intuitive.

"My GPS hasn't updated in 45 seconds... maybe I'm in a tunnel."

That would only require one glance to get the answer.

Otherwise one would need to remember the number on the screen, and then look again and see if it is the same number, a little later. And also such numbers are not important in the first place: sort of like those one-time throwaway SMS codes: 761141.
