Yes, this sounds reasonable.
As far as I remember BTB does not support these dynamic TV (replay) cameras.
This information is located in the DLS files as well, but is not populated with data by the BTB track editor.
Best would be to drive in recce speed ~50 km/h or maybe slower. Then all callouts should be consistent while testing.
In contrary to vanilla RBR the plugin actually emits the pacenotes during replays (can be muted via menu for viewing replays).
Remember to save your changes before you leave the stage.
