How do you measure X-factor? Does it come in units or is it a subtance. Does Glenn Maxwell give you one X-factor or does he provide you with a few centilitres of X-factor that you can pool along with whatever can be provided by Mitchell Johnson, David Warner and Xavier Doherty?

Either way, the team with the most X-factor will win this World Cup. From what we’ve read, there will be a direct correlation between it and results – that much is clear.

But which players possess X-factor? Our feeling has always been that you either have it or you don’t, but today Cricinfo are asserting that Luke Ronchi is evolving into New Zealand’s X-factor which suggests that you can gradually attain more and more of this quality.

A friend of ours used to work in a nursery. She was forever losing her rag with three-year-olds pretending to be Pokémon (Pokémons? What’s the plural?). They’d squat down, do some sort of weird vibrating mime and say: “I’m evolving!”

“No, you’re not,” she’d spit. “You’re metamorphosising!” Then she would start talking to them about genes and natural selection.

So perhaps Luke Ronchi is evolving in the Pokémon sense and will emerge as a fully-formed X-factor player at some point soon. Or maybe it really is a gradual process and one of his hollow limbs is slowly filling with more and more X-factor fluid.

Whichever it is, we can state only one thing with confidence: very few of our World Cup cricketers to watch are X-factor players.
