Which is (for various reasons) why I've said in previous posts that it is best to ignore the screens, just be at the gate at least 21 minutes before departure unless you know there is a delay - rather than the other way around as indicated here. And if it is a bus gate you probably need to add a few extra minutes just in case. Work backwards from the timings from each lounge, which in the case of the B lounge is 5 minutes, so 26 minutes to departure.
