Yup, the settings file prefers 4-game series against divisional opponents, and 1-game series against interdivisional opponents. A limitation of the code is that it prefers to play two or more series against every opponent, and changes the pool sizes to do so, so it can't generate a schedule, just yet, where a team plays e.g. a single two-game series against a large number of other teams. In that case it generates smaller pools and falls back to the uneven-pool scheduling code, as described in the readme, yielding some teams with matchup counts like this, playing six opponents, including one divisional opponent, five times, and some which play five opponents, including one divisional opponent, six times.
