14	-0.028	1.827 ± 0.058 (n = 5)	1.855 ± 0.034 (n = 5)	-

n represents the number of samplings in each group.

The significant difference means the probability that the difference in means between the two groups is caused by coincidence due to sampling error, and 5% is used as the significance level.

@keichan34 @naogify この筆ポリゴンのサイズは 3/4 になりましたが、高ズーム&田畑のある場所でベンチマークを回してみても結果は変わりませんでした。ただ、ネットワークトラフィックは減るので、マージするメリットはあると思いますが、どうでしょう？

Oceanus に取り込んだり、タイルサイズの制限を設ける件もあるので、その辺りと一緒に解決することにしたい。
