I read the speed skating and biathlon, since I don't care much about figure skating I probably won't read those
I only had a tiny remark or two:
That's basically like saying "skiing fast is critical to a good result in alpine skiing" or "climbing well is critical on a big climb in road cycling". It has nothing to do with this format, it's simply a part of the sport. Plus the first sentence makes it sound like the format meant the lead changed at every exchange, but that's not the case. It sometimes happens, it sometimes doesn't.
Mind you, those are only small things, I thought the articles were excellent to read
