crystalmathlabs

I've been trying to find a site where you can compare weekly xp gained in specific skills against other players. I've heard of crystalmathlabs and was under the impression this was the goat. Do you have to manually sign up for it to track your progress? I can't find any of my accounts on here. Also, I can only find overall xp which I can see on the osrs homepage so that's irrelevant. I want to know how to see weekly hiscores. If anyone knows how this site works PLEASE explain it to me. Thanks
