JTs against 87s: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| JTs | 63.312 | 1.134 | 35.554 | 63.879 |
| 87s | 35.554 | 1.134 | 63.312 | 36.121 |

| 87s | 9,741,000 | 311,000 | 17,346,000 |
Exact total: 16 deals times 1,712,304 boards. The other three counts come from the five-decimal percentages and are rounded to the nearest thousand, so read them as approximate.
