If you look at the bid history, there was a jump from 4400.00 to 10,000.00 made by a new identity bidder. I would say someone was fishing for the reserve. A bidder can make a high proxy bid like 10k, if the reserve is 5500.00, that will become his bid. If someone bids higher, his bid moves up until he hits his 10k max. Also, he can through out a big number, discover reserve and then retract his bid.
