Revisiting this topic after listening to @JeffParsons discussion with @JLemire on Pinball Player’s Podcast. They talked about having the SW ball-save logic be similar to Congo’s – where a player can get more than one initial ball-saves based on what’s been hit. This was also suggested in this thread’s original discussion from May’18.
However, I think that the best solution is similar to what @mizary suggested above, in changing the SW initial ball-save to an adjustable timer that will provide unlimited ball-saves during that timer (similar to TNA’s initial ball-save implementation, as well as JJP’s initial ball-save logic) instead of just one ball-save.
The reason why a Congo-style ball-save isn’t the best solution is because any of us who have studied at the Cayle George Institute of Invalid Playfields will find a way to exploit a “minor switch means your PF isn’t valid” logic.
Especially for those of you operating SW and see casual/novice players suffering from death-by-plunge on SW, what say you? Perhaps we can get Dwight (or another Stern programmer to code this in).
