I accumulated them myself.
Those are ~correct as of the 10th of December (last big break and where I got up to. Done none since.)
SHL flash the leaders up on screen during games at times and a few SHL analysts tweet some out at times as well, so I can check them off that to see how close I am to the obviously kept 'official' ones.
Hopefully I can do the whole season... but it is time consuming and I am moving countries in seven weeks to a new job!
The other two SHL Dmen on the WJC roster are impressive too though (as of December 10th):
Dahlin: 61.67% CF, +10.54 CF Rel
Brännström: 54.8% CF, +0.97 CF Rel
