Before the update, optimal solutions required ~1200 cycles and 20-24 cost. After the update, we know that we can achieve ~1200 cycles with costs in a wider range 20-112 and still be optimal - that is, cost plays a lesser role in achieving optimal solutions. Consequently, rooted solutions that are faster at the expense of having higher cost get better scores now.
Getting 360i for a rooted solution suggests that it was treated equivalently to an optimal solution. Is the cost*cycles product of your solution around 24*1200?
