The assumption is of uniform distribution. Doing more did not seem necessary.
In Tables 7 and 8 of the special masters' analysis can be found another way of estimating these probabilities. There they get 8/8 (100%) Republican majoritarian, 11/17 (65%) Democratic majoritarian. https://acefiling.wicourts.gov/document/uploaded/2023AP001399/760087#page=17
The Wilson score estimates on these probabilities are 94+/-6% and 64+/-11%, respectively.
