| The PORIZ rating system was developed
specifically for amateur sumó, based on statistic analysis of past match
data.
The system enables most of all direct comparison of
individual athletes throughout time, even though the athletes might never
have met.
This way, a historic TOP list can also be constructed
for the purpose of comparing past and present amateur sumó wrestlers. |
