Such incredible performances are actually very rare. We see many performances where either the top order batsmen play well and if not, the middle order or lower middle order batsmen score well and the team can finally give a good target.
But we rarely see such matches where three top order batsmen score centuries, and the fourth batsman scores a half century. From my point of view, this is one kind of record. Anyway there journey is not yet ended  rather I would say that  their real challenge is going to coming in the New Zealand series.
