Since all 3 cranes are luffers, they have a lot of flexibility. I would expect that we will always see the taller one jump first and the medium one jump second. The towers should rise roughly floor for floor once the climbing cores are both built (barring unforeseen issues). The small crane is probably at it's ultimate height since it is only there for a short time to support the podium.
