Any ability to auto update this data daily? Or document for those that can pull their own and implement into the addon?

Looks like
LogTracker_CharacterData_US hasn't been updated in almost 1 month.

People are asking updates on reddit too. @ForsakenNGS how can we help you to update data?
If you can give/open source the scraper we all can pitch in! And maybe change the update to weekly rather than daily?

See #13 I could release the code, but it breaks the TOS of warcraftlogs and may result in the account being banned. Until there is an official data source that allows this, I will maintain the freshly released intermediate solution that just shows the raid progression.
