If I purge all observed hands, will it affect my HUD stats? I have a ton of custom stats and kind of need the observed hands, but wanted to trim down my database size. I know that for HEM, purging only affects your ability to view a hand and leaves the HUD stats the same.

Purging removes the hand completely - retaining a "memory" of stats from hands which are no longer in the database has the potential to cause complications. If you add more stats the purged hands obviously won't be available so you could end up with mismatched information.
