rule "in order to encourage variety and balance rather than allowing a skater to rack up credit for demonstrating the same skill over and over". Kestnbaum also says that as rotations in jumps for both men and women have increased skaters have increased the difficulty of jumps by adding more difficult combinations and by adding difficult steps immediately before or after their jumps, resulting in "integrating the jumps more seamlessly into the flow of the program". In both the short program and free skating, any jump, jump combination, or jump sequence begun during the second half of the program earns extra points "in order to give credit for even distribution of difficulties in the program". As of the 2018–2019 season, however, only the last jump element performed during the short program and the final three jump elements performed during the free skate, counted in a skater's final score. International Figure Skating magazine called this regulation the "Zagitova Rule", named for Alina Zagitova from Russia, who won the gold medal at the 2018 Winter Olympics by "backloading" her free skating program, or placing all her jumps in the second half of the program in order to take advantage of the rule in place at the time that awarded a ten percent bonus to jumps performed during the second half of the program. Also starting in 2018, single skaters could repeat the same two triple or quadruple jumps only in their free skating programs. They could repeat four-revolutions jumps only once, and the base value of the triple Axel and quadruple jumps were "reduced dramatically". As of 2022, jump sequences consisted of two or three jumps, but the second or third jump had to be an Axel. Jump sequences began to be counted for their full value and skaters could include single jumps in their step sequences as choreographic elements without incurring a penalty. Junior men and women single skaters are not allowed to perform quadruple jumps in their short programs. Senior and junior men and senior women must complete either a double or triple Axel jump in their short programs, but junior women must complete a double axel. Male and female junior and senior skaters must include a "maximum of seven jump elements (one of which must be an Axel type jump)" in their free skating programs. Both junior and senior skaters receive no points for jumps performed during their short
