Whether in the last few seconds or not, you seem to believe that manual bids have priority over automatically generated ones, so that later manual bids can still trump a higher previous one. > The computer begins toggling all those through a > chronological seine based on server arrival time and as the close of > bidding stops, so too does any processing of any bids currently being > processed into the system sitting in the queue. Even though the "auto" bids are sitting on their servers already, timestamped and waiting, your last-seconds bids take priority. You have absolutely no evidence for this behaviour, which goes against the whole rationale of the bidding process. > Last second bidding used to be the only way to get an item at a decent > price. > > If any two auto-bidders bid early in the game (auction), their bids > will auto-increment up to the max that the top bidder of the two has > set. Yes, immediately. > That is why you do not see any bids by them early in the game EITHER. If they bid early you see bids by them, up to a bit more than the lower of the two. > That drives up the last seconds bidding was starting price, so nobody > enters auto bid figures early in an auction.

This is what I already told you was the optimum strategy, although I am now not quite sure what you think you mean by an "auto-bidder". All bids are "auto-bids", unless you bid exactly the amount shown. > NOW are you starting to get it? -- John Devereux
