There's also a difference in how you describe the rounds. In Cambridge, after the initial round where any candidate who got over quota in #1 votes is elected, and the second round, where all candidates with fewer than 50 are eliminated, each round is the elimination of exactly one candidate. Their transfer votes can elect 0, 1, or more other candidates, but that doesn't affect the fact that the next round will again be the elimination of exactly one candidate. The process continues until all seats are filled.
The "random transfer" in Cambridge is actually not random, nor is it stack or queue. It's a systematic transfer of whole votes rather than a wholesale transfer of partial votes. The randomness is in the order of ballots cast: to transfer 1/3 of the surplus ballots, for example, transfer ballot #1, #4, #7, etc.
