I’m slightly surprised by this as I remember Latham getting a huge unbeaten double ton in his debut season that I remember bumping his FC average up to 40ish, but thinking about it I suspect that was probably made after his test debut in the last round of the Plunket Shield.
Edit: this game, which came the week after his debut:

I guess one difference between Latham and Ravindra was the former really piled up mountains of runs that season. Scored nearly a thousand at 79, making it pretty clear he was ready for the step up. Rachin’s never managed to have a bumper season like that, he’s just been quietly oscillating between very good and ok.
