We are using Airtribune Live Tracking track logs are the primary
means of scoring the competitions in Florida. Pilots get a 1% penalty if they
don't have a valid Live Tracking track log and need to send in their flight
instrument's track log as a backup.

They do not get a penalty if the fault lies in the Airtribune server or in the
FS scoring software, which can't handle relaunches. They do get the penalty if
it appears that the problem lies with their phone or tracker. We are not able
objectively to determine if the fault lies with their phone or with how they
started the App (or not).

We've also noted that there are track logs with large gaps:

From the 2017 CIVL Plenty minutes:

“Flights will be verified using either GPS track log or livetracking data. When
live-tracking data is used as a primary source of scoring, pilots must be able
to produce GPS track logs as a back-up.”

From the local rules for the 2017 Worlds:

“The tracklogs of the Live Tracking devices will be used as the primary source
of scoring.”

“Every pilot will be responsible for using and properly carrying in flight the
Live Tracking devices&hellp;”

I would suggest that they might run into the same problems that we do, although
not with relaunches most likely unless pilots top land.
