We conducted this survey,Slate MagazineBen Blatt who has posted numerous articles on. Blatt obtained a game record by a professional bowler preserved by the American "American Pro Bowlers Association" and succeeded in finding the "form of split that is hardest to beat" by analyzing the record of 447,000 frames I heard he did.

Actually, there are various forms of "split", but generally speaking of split the leftmost and rightmost pins remained one by one "7-10 splitIt is often noticed to think of "the rest that is thought to be the most difficult to defeat" is not an overstatement. When calculating the "spare rate" which succeeds in knocking down the remaining pins in the first round, we found that the spare rate of 7-10 split was as high as 0.7%.


However, it was found that if the actual record was intensified, there was even more difficult split. The top 10 of the most difficult split rankings created based on the records summarized by Blatt was as follows.


The reason why the most difficult split was certified is that the 4, 6, 7, 9, 10 pin remained "Greek Church(Greek church) "Split named, its success rate is how0.3%. Even if a professional challenges, the achievement that three times only one thing in 1000 times has not succeeded tells the height of the hurdle. The aforementioned 7-10 split, aka "Bed Posts(The pillar of the bed) "is attached to 3rd place, I know that it was still difficult. It is quite interesting that the shapes of the 2nd and the 4th are reversed left and right.


When it comes to "Big Four" with a success rate of 1.0%, it seems to be easy to understand, but it is still the probability that a professional will challenge 100 times and succeed only once. The "Greek Church" underneath it was in a state where the order of the 1st place was reversed, and the difficulty became about half by only turning in the opposite direction, this also proved interesting.


As you can see, split is a difficult situation for professionals. Such PBA's professional bowlers are fascinated7-10 Split makeYou can enjoy yourself in the following movies carefully.

Conversely, a list of combinations that succeeded in spare with the highest probability with three or more pins remaining, including split, is here. "1-3-9" in the first place is a spare ratio of 89.2%, and if you remove it it falls into a situation where you can press a ruler of "professional disqualification", so it seems better to take precautions.


In addition, among the 447,000 frames analyzed by Blatt, it turned out that a frame of slightly less than 60% recorded the strike. It is a record that arouses professional awfulness, in other words, it seems to be said that the difficulty of split that can not be defeated even by such a professional is transmitted analysis result.
