Only matches for past 5 years from current date are taken into account.

|
An analysis of past results shows that winning away is 50% more difficult than
winning at home. Therefore 3 points are awarded for away match wins, while 2 points
are awarded for a home match win.
|
|
3.
|
Winning a series away earns a bonus 3 points, while winning a series at home
earns a bonus 2 points. See 2 above.
|
|
|
Note: Two or more matches must be played to constitute a series - one-off
tests are not counted as a series.
|
|

|
For each year after the current year, points earned are deprecated by 20%.
(e.g. for a result between 1 to 2 years ago points are deprecated by 20%,
for a result between 4 and 5 years ago points are deprecated by 80%).
|
|
5.
|
Points from a series (i.e. 2 or more matches) between two countries in a given
country replace the points for the previous series between the countries in the
same country.
|
|
|
For one-off tests, points do not replace those from an earlier series, but are
cumulative. This means that a country which has earned points from a previous
series win, is not penalised for subsequently losing a one-off test against the
same opponent at the same venue.

|
As some countries play a lot more test matches than other countries, a weighting
system is applied by dividing the total points earned (during the past 5 years)
by the number of matches played by the country during that time. The resulting
value is multiplied by 100 to give the HowSTAT rating.
|
|
|
Example: In a given 5 year period Sri Lanka has earned 28.00 points and played
36 matches during this time. 28.00 divided by 36 multiplied by 100 gives them
a HowSTAT rating of 77.78.
