브롤스타즈에는 파이퍼라는 브롤러가 있다 그런데 공격력이 거리에 따라 달라진다. 

구간

거리[10][11]

최대 피해량 대비 피해 비율[12]

초근거리 (1단계)

0~5 (0~1.67)

29.8%

2단계

5~7 (1.67~2.33)

36.2%

3단계

7~9 (2.33~3)

42.6%

4단계

9~11 (3~3.67)

49.0%

5단계

11~13 (3.67~4.33)

55.4%

6단계

13~15 (4.33~5)

61.8%

7단계

15~17 (5~5.67)

68.2%

8단계

17~19 (5.67~6.33)

74.6%

9단계

19~21 (6.33~7)

81.0%

10단계

21~23 (7~7.67)

87.4%

11단계

23~25 (7.67~8.33)

93.7%

최대 사거리 (12단계)

25~30 (8.33~10)

100.0%

 그러나 거리가 1일때는 100%로 맞추나 2일때는 90%, 3일때는 80%...10일때는 10%이다. 공격력의 기댓값이 최대가 되는 거리는? (표에서 괄호안 숫자로 생각합니다.)
