You're welcome.
I'm even more confused: either I did not see the graphic or the one I get from my local cable provider is different (I don't think so, but...). As far as I remember, they just show (once every blue moon) the name of a driver, the gap and the name of the follower.
I'll check next GP and let you know. I don't know the numbers of the drivers, never did, never will (I assume Kimi is number one

). All I know are the helmet patterns (and not very well) and sometimes I check the colour of the cameras (they are different among members of the same team, as you might have noticed).
NASCAR has a more readable strip on top of the screen, but it also annoys me because it's there all the time, and while you wait to find out where a driver is you miss a couple of laps.
If you're planning on complaining to FIA, please, let them know that I also find curious that they don't show all the overtakings, but just a few, even if that has also improved slightly.
