Oh, a random note that people might find hilarious or humanizing, a winding road is not a perfectly uniform length. It's edges will be different lengths from it's center, meaning that the hundred soldiers cannot maintain both perfect formation and synchronicity while travelling on the same road. If they maintain perfect synchronicity, then the soldiers on the outside of the formation will fall slightly behind or ahead, as they will have traveled a longer or shorter road than those in the center. If they maintain perfect formation than the horses on the outside must increase and decrease their speed as they take corners, causing their hoofbeats to fall out of sync with the others in the formation.
This means for the unit to have both perfect formation and synchronicity as they reached the Sect town, the moment they hit the last straightaway the group had to immediately fall into formation and then synchronicity... simply for the purpose of appearing to have always had perfect formation and synchronicity. It's an interesting vanity that's easy to miss if you don't think super hard.
