David, the fact that you can construct an example where it works out the same does not disprove the proposition that sniping provides some measure of protection. You're smarter than that. Obviously, it cannot protect against a hidden reserve, but at the same time it can protect against someone running your early bid up to see how high it is, then retracting and exposing it so it can be run up again to just under the max. Your hypothetical assumes the consignor or seller won't let it go below a certain amount. Not always the case -- sometimes the consignor or seller just wants to maximize.
