I think I've identified a potential bug in how the blunder database handles XGID score imports. When checking my missed cube decisions:

The XGID imports match scores in reversed order

Even after manually correcting the scores or leaving them reversed, XG's blunder assessment marking the opposite of what is reported on the hub blunder analysis.

XGID=---BaCCB---abBb----cbC-bb-:1:1:1:54:8:5:0:11:10

Could you verify this behavior? I can provide specific XGID examples if needed.
