from the Q&A:
I still stand behind my idea to eliminate step putts, but would love it if somebody could poke some holes or tell me it's stupid for certain reasons
It's stupid. For reasons.
Fundamentally a step putt and a jump putt are no different than any throw from outside C1. There are probably plenty of occasions of stance violations well outside C2 where a player doesn't actually plant inside their lie, but you can't usually see them, so you aren't worked up about them.
You seem to want to enforce some hypothetical rule of verticality for feet only, but that will likely just lead to another ambiguity about whether someone's foot was past the vertical plane of the lie when they released.
Another theoretical rule, that two contact points must be maintained at release, is completely unworkable, as it would eliminate essentially all stagger stance putts and most regular throws.
All of this to solve a problem that is only a problem in the sense that people get worked up about it. The advantage gained from the decreased distance, if any, is
de minimus.
Jump and step putting are exciting skills to have in the sport. Nothing quite so satisfying as canning a long putt made possible by the momentum gains from not preventing follow through to after the lie.
Given that, I'd argue that the preferable rule change (if any) would be to specifically make jump putting legal. So long as your
last contact point was in the lie, actual jump putting would be legal outside of C1. C1 rules would remain as is. This wouldn't actually change much at all (although I suppose a putter like James Conrad might prove me wrong.) Perhaps one could add in a qualifier about first making contact again with the playing surface (after releasing the disc) within 1-2 meters of the lie to prevent actual flying putts. Although honestly, if anyone could make those work, they might be pretty cool to see.
To be clear, my stance is always that the existing rules are likely to be sufficient, so this is all hypothetical.
