Others, however, disagree. I (and many coaches) think that the scoring of combinations and sequences is not correct. That is, does not correctly reward those elements. There are proposals circulating to change the scoring of combinations and sequences.
Doing two jumps with turns and steps with the rhythm and continuity required to be called a sequence is not easier than doing those two jumps as two completely separate items. At a minimum the sequence should receive as many points as the two jumps alone.
Doing two jumps in combination is more difficult than doing those two jumps alone, and should be worth more than the sum of the points for those two jumps alone.
If I correctly understood comments Alexander Lakernik made at a meeting on IJS in Dortmund, it was decided to limit combinations to the sum of the points of the jumps, because the number of points earned by jumps in total was getting worrisomely large. Then, since sequences are easier than combinations they had to get fewer points, hence the 0.8. Thus, there was a conscious choice early on to undervalue the combinations, which dragged down the sequences with them. (In other words, it was earier to undervalue the combinations and sequences at that point than to revamp the entire point structure to get it right!)
