I'd say that in sequence would mean directly back to back. However, this could be a place that, with cleaver wording of your ASL, it could be okay. For example, if you put the levers and their non-scorable tasks in one step, it would be considered one step. But going back to the first point, it is safest to put them all directly after one another, be it with string or direct contact.When it says to use all 3 classes of levers in sequence to initiate the next action, does in sequence mean directly back to back or could I have non scorable actions in between? For example, could I have a ball triggered with the first class lever and then could the ball activate the second class lever?
