Where do you start? Automatic adjustments? What's your first hurdle?

I love working on Pianoteq presets. It's my obsession these last few months or so. Before I ask this open question, let me ask a rhetorical one. How amazing are the official Pianoteq workshops? https://www.modartt.com/pianoteq_workshops Even multiple versions of Pianoteq later they ring true. Working Big to Small makes a lot of sense when creating a new preset with possibly hundreds or even thousands of steps in that process. Why? Big choices also eliminate massive amounts of small choices.

Questions for you:
1. What drives you when deciding to work on a new preset lately?
2. What are your "go to," automatic adjustments?
3. What's your first slow hurdle to work on?
