The cold timer is the part I'd stress more than the platforming itself. Thirty seconds sounds workable until you stop to line up a Clawline hook, and sudden panic is what usually kills the attempt. Taking the climb in short, deliberate bursts and retreating to warm up beats rushing the whole ascent in one go. Also worth noting the Weavelight advice applies to the hook timing here, not just silk recovery, since a missed grapple mid-climb is far more punishing than a slow one.
