advantage to competitors, points are subtracted when the starting gate is moved up, and added when the gate is lowered. An advanced calculation also determines compensation points for the actual unequal wind conditions at the time of the jump; when there is back wind, points are added, and when there is front wind, points are subtracted. Wind speed and direction are measured at five different points based on average value, which is determined before every competition. If two or more competitors finish the competition with the same number of points, they are given the same placing and receive same prizes. Ski jumpers below the minimum safe body mass index are penalized with a shorter maximum ski length, reducing the aerodynamic lift they can achieve. These rules have been credited with stopping the most severe cases of underweight athletes, but some competitors still lose weight to maximize the distance they can achieve. In order to prevent an unfair advantage due to a "sailing" effect of the ski jumping suit, material, thickness and relative size of the suit are regulated. Techniques Each jump is divided into four parts: in-run, take-off (jump), flight, and landing. By using the V-style, firstly pioneered by Swedish ski jumper Jan Boklöv in the mid-1980s, modern skiers are able to exceed the distance of the take-off hill by about 10% compared to the previous technique with parallel skis. Previous techniques included the Kongsberger technique, the Däescher technique and the Windisch technique. Until the mid-1960s, the ski jumper came down the in-run of the hill with both arms pointing forwards. This changed when the Däscher technique was pioneered by Andreas Däscher in the 1950s, as a modification of the Kongsberger and Windisch techniques. A lesser-used technique as of 2017 is the H-style which is essentially a combination of the parallel and V-styles, in which the skis are spread very wide apart and held parallel in an "H" shape. It is prominently used by Domen Prevc. Skiers are required to touch the ground in the Telemark landing style (), named after the Norwegian county of Telemark. This involves the landing with one foot in front of the other with knees slightly bent, mimicking the style of Telemark skiing. Failure to execute a Telemark landing leads to the deduction of style points, issued by the judges. Major competitions All major ski jumping competitions are organized by the International Ski Federation. The
