I'm not sure about the ultra-high end auction market (5+ figure stuff), but I can tell you for sure the handling of how auctions actually end balancing East Coast vs West Coast time zones is leaving some real money on the table from East Coast people bailing on the ones that can linger deep into the night...especially the "all lots open until auction ends" stuff.

I'm sure the action houses have done their internal math and can "actually..." a financial benefit, but I've talked to many fellow East Coasters who can't afford to win everything they're bidding on, but can't stick around until the middle of the night to see what's left in range...and they end up getting not much or not anything at all

As far as BP, it seems the plus/minus depends on how well you can negotiate with a given auction house and/or play ac's against each other for the biggest cut. That's a very dynamic thing even if most of what we see at auction don't have that kind of leverage for a huge cut in the negotiation...plus some cosigners may give up some of that possible cut for more publicity for their lot(s)...
