I guess I am one of those irratating bidders.   My theory is to come up with the max bid I am willing to pay.  Knowing there are others out there doing the same thing.  Wait till the last 5 seconds ( it's all manual ) and hit bid.    That stops me and another bidder getting into an auction frenzy.   I have placed my max bid and I can not go any higher because the auction is finished.  You can do the same.
