This calls for awareness of what your opponents might be holding in addition to self-assurance in your own hand. Also, when determining whether to declare Rummy, take the current state of play into account. It might be timeexpansion slots for you to declare if you've noticed that opponents are having trouble forming their own melds or appear hesitant in their moves. On the other hand, you might want to wait until you're more confident in your own hand's strength if you've observed that they are moving quickly toward their own declarations. In the end, developing the timing of Rummy declarations requires striking a balance between confidence and astute observational abilities.
