Trouble with only announcing the top 5 in each class is that if your favourite car or team isn’t in the top 5 you won’t have a clue what is going on! And a lot of us follow the smaller teams. With 55 starters you are immediately ignoring 35 cars! More than half the field, I know that they won’t all survive the full distance, but for the first few hours at least they will get ignored. The top 5 in LMP1 is going to be the 3 Audi’s and Two Pugs (Until 1 or more hits trouble), so if like me you are a Rollcentre fan then you won’t know where they are unless you can get to a timing screen.
Personally I’d rather see a full rundown of each class but at different times, say on the hour for LMP1, ¼ past the hour for LMP2, ½ past the hour for GT1 and ¼ to the hour for GT2, that way everything gets covered and if you are interested in a team then you know what time to tune in and listen (presupposing you’re not listening for the full 24hrs that is!)
