About This Site

"Data Oyakata" is a bout of sumo wrestling.dataandData Oyakata (Data Predictions)This is a site to enjoy. We will deliver Kunio Makuuchi's wins and losses probability, rikishi's Record, and "Data Insights" that confirm the popular theory with data.

Data Oyakata is not a betting tool. It's a bit of a nuisance to make sumo more interesting.buddyIt's like. ``This rikishi is strong on Final Day'' ``It's actually stronger than Banzuke'' - we will gently help you make discoveries based on numbers.

Predictions are published using only the data known before Basho started. The winning rate is approximately 60% with Makuuchi Kunio. The remaining 40% won't win. But sumo is fun because you don't get hit. I hope you enjoy it, including the "unreadableness".

How Predictions works (roughly)

First, let's look at each rikishi's "current strength".「Strength index」Let's make it a number. every boutwins and losses aloneIf you win against a strong opponent, your score will rise significantly, and if you lose to a weaker opponent, your score will drop significantly.It is a system that takes into account the strength of your opponent and updates it (this is an adaptation of the ``Iro Rating'' used in chess etc.).

Based on this Strength index, we calculate the probability that both players will win by adding their recent record, physique, past matches, etc. Since we do not use Banzuke (a rating determined by people) and measure only by the accumulation of wins and losses, we can quickly show "growth" and "decline" before they appear in Banzuke.

And the important thing isPredictions are made using "only data before that Basho"Things. Since we do not guess the answer after knowing the answer, the percentage of hits displayed is close to the actual ability when using the game.
