I was just rabble rousing, but thinking it through a bit more:
1. It's probably wise to throw a link to the league in there. They're generally there for a good long while, though the format changes every now and then so you can't always suss them out on a look-back basis. Such as
https://www.velogames.com/catalunya/...ague=539488111
2. The options from those league pages give you the stage results. They don't capture the GC-to-date. So maybe I was on to something! Or perhaps just on something.
