England poised to be the best in the world - ever

After last nights 16-13 win over New Zealand the England are on the verge of becoming the best in the women's rugby team in the world - ever.

This is really one for the statistical geeks out there, but since women's test rugby began 30 years ago the "league table" of the most successful teams (that have played 20 tests of more) looks something like this:

In fact the top six have been pretty much unchanged for the past 20 years or so, but if England were to win the current series 3-0 we would see the first significant change for two decades. For the first time ever England would go top. 

England's record would go up to 87.56%, while New Zealand's would fall to 86.72%.

Even if England were to win only 2-1 the gap would close to barely one percentage point, which is pretty remarkable as after the World Cup the gap was nearly 10 points.
