How does the scoring work in skating?

I don't have a clue.

All I know, is that there are two different systems in Canada right now. Very low level skaters use an older system. When they compete, the only results that are announced are the rankings of all the skaters.

No other marks are given. At higher levels, the rank and a score are publishied. A detailed result is also published which is a matrix that shows the scores awarded by each judge for each element in the routine as well as a total score. Here are some examples of a result listing and a detailed result.
