You may be able to cut your list of competitors in half, but there's one problem with that strategy.

The seven guys you knocked out were probably tire kickers looking for a good deal. The seven guys who are left are the whales who will go really high on the lot. So you have accomplished nothing.

If you bid often enough to knock out thirteen bidders, and only one is left, but that one bidder has all the money in the world and won't let that lot go to anybody else, you've still accomplished nothing.

It's generally a strategy that doesn't work. Whoever are left are the guys who are going to make your life miserable. The ones you cut out are irrelevant.
