@jacob.hart has very kindly shared his code with me, and I’m going to try and make it a bit faster; with his agreement, we’ll probably include it in the main distro. However, this is Max: I still need to harness enough SC gui-fu to assemble something that would be useful to @spluta.
@rodrigo.constanzo is quite right that being able to see the feature curves themselves would help massively with this, partly because thresholds and curve shapes are so different for various metrics. In my mind, there’s a sort of two-phase idea. The long term idea is a breaking change, where we separate the business of cutting curves from the business of generating them (more flexibility, but also more objects to learn). In the nearer-term, it would probably be possible to simply equip the slicers with new, secondary outputs, without breaking too much of everyone’s stuff.
