ボートレースのイン逃げ率（1艇1着率）はだいたい54％くらいっていうのは知っていたけど実はレース場によって結構差があります。
大村、徳山、芦屋はイン有利
江戸川、戸田、びわこはインが強くない
というのは有名な話だけどそんなに差あるの？
と思って調べてみました。
2019年の全レース！
| 順位 | イン逃げ率 | |
| 1 | 大村 | 67.0% |
| 2 | 徳山 | 63.0% |
| 3 | 芦屋 | 61.7% |
| 4 | 住之江 | 58.8% |
| 5 | 蒲郡 | 58.4% |
| 6 | 下関 | 57.8% |
| 7 | 津 | 57.7% |
| 8 | 児島 | 56.7% |
| 9 | 常滑 | 56.2% |
| 10 | 尼崎 | 55.8% |
| 11 | 宮島 | 55.2% |
| 12 | 三国 | 55.0% |
| 13 | 多摩川 | 54.4% |
| 14 | 福岡 | 54.3% |
| 15 | 若松 | 53.7% |
| 16 | 丸亀 | 53.2% |
| 17 | 唐津 | 52.9% |
| 18 | 浜名湖 | 50.9% |
| 19 | 桐生 | 50.2% |
| 20 | 江戸川 | 49.4% |
| 21 | 鳴門 | 48.6% |
| 22 | 琵琶湖 | 47.6% |
| 23 | 平和島 | 44.8% |
| 24 | 戸田 | 42.5% |
戸田と大村だと24.5%も差があるぅ～。
さらにこの結果、月間で見るともっとばらつきます。
これが月別だ！（超見にくい）
大村や徳山は70％超える月があるからそりゃ1号艇から流しますがな。
ただ、これは季節が関係しているのかその時に開催されているレースの番組に起因するのか要因がいろいろありそうなので「8月の大村はインしか買わない！」とも言えないのでもう少し実績を見ていく必要がありそうです。
