看来我也老了。57人中年龄排22位。
no, even with equal range, we may calculate your age ......

say around


21 + 14 * 10/17 = ??? or 35 - 14 * 7/17 = ???


as your group of 17 (No 16 to No. 32) players is within the range of (21 to 35 years old).

Of course, another simple way is mid-point of (21 + 35) = ???

but if we study the distribution more closely, since only 5 players within the range of 35 to < 50, so for the 17 players within the range of 21 to < 35, likely more records will be closer to the end of 21 but not the end of 35.

So, logical guess is your age should be below the mid-point. :P

-----------------------------------------------

50 years old or above -- 10 players (two special prizes if none qualify for other prizes)

35 to < 50 -- 5 players

21 to < 35 -- 17 players

15 to < 21 -- 17 players

< 15 -- 8 players (one special prize if none qualify for other prizes)
