It is common to find progressions where the same roman numeral repeats itself:

I think in these cases, a common procedure for "good" voice leading is to prefer a change of the voicing (e.g., change of position in the three upper voices), penalizing the algorithm for proposing the exact same voicing twice.

I wanted to make sure that the policy coincides with the practice in existing music.

I looked for repeated harmonies like these in 69 annotated Bach Chorales and found 192 instances.

Out of those 192 instances:

  • In 78% of them, the voicing changes
  • In 22% of them, the voicing remains the same

Here are a few of the instances I found. Red means different voicing and green means same voicing.

For completeness, here is the full table. Offsets are given in quarter notes from the beginning of the score (starting from 0.0). In all instances, chord1 and chord2 are contiguous and annotated by a human expert:
