Tenhou log stats

1. Open the game in Tenhou's replay viewer and copy the address. It looks like https://tenhou.net/0/?log=2026010112gm-00a9-0000-1a2b3c4d&tw=2.
2. Paste it above and press Show my stats.
3. The tw= number at the end is the seat the replay opens on, so the stats open there too. Pick another seat to see that player's numbers.
4. For a bigger sample, pick Up to 5 games and paste one link per line. Each link's tw= number picks your seat in that game. A link without one starts on East and gets a flag, so check the seat there.

• Placement: where you finished, your final points, and the game result Tenhou prints next to your name, such as +24.0.
• Wins and deal-ins: hands you won, and hands where your discard paid someone's ron. A tsumo you pay for isn't a deal-in, and a double ron counts once. Rates divide by every hand dealt, abortive draws included. Averages use the hand's value before honba and riichi sticks.
• Riichi: riichi you declared, and how many of those hands you won. A declaration whose tile deals in still counts. Tenhou's own stats page counts only riichi still standing when the hand ends, so its riichi rate can read a little lower.
• Average place, over several games: your places added up and divided by the games, the way Tenhou's stats page works it out. Game results are Tenhou's, added up.
• The bars: each one is a 95% range for your long-run rate, worked out from the hands in your sample. Ranges built this way contain the true rate about 95 times in 100. The dot is what your hands show. Over one game the bars are wide. They narrow as the hands add up.

One game is too few hands to separate a leak from a bad run, and five games isn't many more. Read the numbers as a summary of those games, not as your rates.
