There's a lot of literature on auction theory. I don't get the sense you've read any of it, or talked to anyone who has.
Ad auctions happen in microseconds. There's no possibility of changing your bid while it's underway.

As the other person said, bids repeat across multiple auctions on the same keyword and even in a generalized second price auction optimally your bids are adjusted based on the expected dynamics of each auction. Based on past information and so on. In a first price auction you’d keep lowering your average bid until it’s on average right above the next bid. The next bidder would then increase their bids. You’d then do so as well. Etc. Etc.
