Whether you treat international cricket's ratings as gospel or gobbledegook, they make fine reading for New Zealand.
Yesterday's updated list shows jumps to No6 in the batting and bowling lists for Kane Williamson and Trent Boult respectively, on the back of strong performances in the second-test win over Sri Lanka in Wellington last week.
Capping that off, New Zealand, as expected have had their step up to No5 in test team standings confirmed.
In the space of back-to-back wins over the Sri Lankans - combined with India getting beaten by Australia in their ill-tempered rubber - New Zealand have jumped two places.
A shame, then, that they won't don the whites again until May in England.
