Minimum Vote Threshold expectation of >=, but uses >

[artoonie]

Bottoms-up using percentage threshold uses a percentage threshold where candidates over a threshold are elected (>). If you also set Minimum Vote Threshold, any candidate under that threshold are eliminated (<).

In Tabulator.java:494:

    // We can never set a winning threshold that's less than the minimum vote threshold specified in
    // the config.
    if (minimumVoteThreshold.signum() == 1
        && minimumVoteThreshold.compareTo(winningThreshold) == 1) {
      winningThreshold = minimumVoteThreshold;
    }

Which says

if (minimumVoteThreshold is positive
    AND minimumVoteThreshold > winningThreshold) {
  winningThreshold = minimumVoteThreshold;
}

This threshold is used as a > rather than a >=. That means if the Minimum Vote Threshold is set to 3, the winning threshold is set to 3, and therefore a candidate must have more than 3 votes to win.

Solutions are to either change the meaning of one of these to include equality, or to implement some special handling of this case.
