You can get an idea by checking out the bid profile of the current high bidder. Just go to eBay Search, select "By Bidder" and enter the high bidder's username in the window, being sure to click on the little round window that says "Yes" for closed auctions. Study the results by looking at the bidding record for a few of the person's successful bids and getting an idea of how close to the end of the auction the guy or gal bids, and by how much of an increment. People don't know it, but they get stuck in bidding patterns that are really simple to uncover and use against them.
