Hi @fpelletier,
Just a minor update on this topic.
@atob reported that lowering the update rate from 10 Hz to 5 Hz helped to get all time marks in the data. The unit currently has V27.0 on board.
However, we don’t have the results of the tests with the latest firmware version — we improved the time marking feature in the V27.1.
I’ll return to this thread if we have an update from @atob.
