CDG on Friday executed group 0 very clearly - much to the annoyance of a group 1 who said "there's a group zero". 2 of us although a wait on the jet bridge to board.

At LHR tonight after a bit of a rush to get through conformance due to problems on the Lizzie line, headed to the gate, plenty of preboards, went to side and said group zero and all of us were able to preboard and whilst not quite first on the plane worked perfectly fine.

I can't actually remember the last time I had a group 0 fail.
