First of all, point values for elements apply only in under the IJS. They are irrelevant to competitions judged under the 6.0 system, where judges just give two marks for the whole program.
Preliminary and prejuvenile competitions in the US are judged under 6.0. So are Open Juvenile at most competitions, although some may treat them the same as juvenile. So are all test track competitions. So are all adult competitions at silver level or below, and many nonqualifying events for adult gold and masters.
If you're over 13 and not ready for standard-track intermediate, or if you're over 18 and not ready for standard-track novice or adult gold or masters, then you do not have to worry about IJS yet.
For future reference, in case you will be competing under IJS in the future, or if you just want to understand how the system works, you should read the documentation at the US Figure Skating Technical Information link I gave in an earlier post. Some of the same documents are available at the ISU Website under
ISU Judging System.
What would the point value be for a spin that is a combination spin. Would you add the points again for each position, or feature, or something else? SO for example if I did a camel,layback, beilmen,fwd.scrath back scratch combo what would the point value be?
Each type of spin has a base mark for level 1. To earn level 2, 3, or 4, you have to include and get credit for performing 2, 3, or 4 "features" to make it more difficult. Look at ISU Communications 1494 and 1557. Some of it has been excerpted into separate links at the USFS link.
The spin that you describe would be a spin combination with change of position and change of foot (element code CCoSp), and it would be level 1 as described, because it only contains one feature (the Biellmann counts as a difficult variation). The base value for a CCoSp1 is 2.0.
Since you already have one feature, if you were planning to do this spin in an IJS competition you might want to try to add another feature to qualify for level 2, which has a base mark of 2.5. Read the latest list of spin features in ISU communication 1557 to see what the options are.
Keep in mind that the final score for the spin would be the base mark plus or minus the average grade of execution (GOE) from judges. So it's only in a skater's best interest to add another feature to go up another level if doing so will not cause a lower GOE that would cancel out the higher base mark.
Keep in mind also that just attempting 2 features won't automatically qualify the element for level 2. The technical panel has to determine that the features were performed well enough to meet certain requirements, e.g., enough revolutions in position.
If you're competing at a level judged under 6.0, there's no automatic extra credit for doing more difficult spins. The judges will each be responsible for deciding how to reward the spins in the context of the whole program, and they'll each balance the quality and the difficulty in their own minds. My observations are that judges tend to be more impressed by good quality than by higher difficulty, especially it when it comes to spins. So under 6.0 it's usually even more true that a skater should only add more difficulty if it won't compromise the quality.
