Based on what I have seen this election and my own bias, I would expect that the algorithm starts at 0% rejection, then calculates 0.15% of the total vote, then deletes that many Trump votes.
The Dominion software was designed to shave votes in 100s of different ways. Find 20 ways to shave 0.15% and you have "found" 3%, which is enough to swing most elections. But in 2020 they had to stop the count and crank up the presses to make up the YUUUUGE deficit!
