Certainty in Dutch auctions concerns not only the identity of the winner, but also certainty in ending the auction itself. Here we present the price of the winning bid in fixed-unit Dutch auctions (Experiment 1) for different starting price bin ranges. We also found no significant difference in either the Price or Step of the winning bid across testing blocks in either experiment. This strikes me as a similar mechanism to the ones you mention (though I suspect it was inspired by Through the Ages). There are a few things we need to cover in more detail.

C., Roberson, B., & Smith, V. L. (1982). Lee, M. D., Zhang, S., & Shi, J. We found no significant difference (\(t = -0.2, p = 0.84, BF_{10} = 0.05\)) between the continuous (\(M = 55.4, SD = 18.75\)) and discrete (\(M = 55.6, SD = 19.0\)) price change conditions on the price of the winning bid (Fig. International Journal of Electronic Commerce, 21(3), 363397.
