Those seeking a "stat of the day" will note when Kane Williamson has scored more than 76 in a one-day international, New Zealand have won 76 per cent of their matches.*
Conversely, of the 31 occasions in 89 ODI innings when he's scored less than 20, the Black Caps' winning percentage drops to 48.
Effectively, New Zealand's chances of winning hinge on Williamson's successes and failures. That is an unhealthy premise if the 2015 World Cup finalists want to continue as an ODI powerhouse.
The remainder of the top order need to deliver more consistently if results are to be based on more complex variables than how the prodigious No3 fares at the crease.
Tom Latham has provided the necessary support in India with ODI scores of 79 not out and 46 to reinforce his test form, but the remainder of the top order - Martin Guptill, Ross Taylor, Corey Anderson and Luke Ronchi - must make improvements if New Zealand are to secure their first ODI series win in India on their fifth attempt. They lost the 1995-96 and 19992000 series 3-2.
