I think death spirals are more like quicksand (in mobies) where once you're in it, it gets increasingly hard to get out with each failed attempt.Because like Rise over Run it's a matter of Degrees.
A Death Spiral describes something sharp and fast. Like that terrible makeshift ramp image I posted. It hastens your journey down to 0hp the entire way, like a ramp at too steep an angle for it's run. You pick up speed as you go and VOOM. Off you go.
Where what I've suggested applies after you've hit the bottom, already. Will it make it harder to get back up? Sure. But it didn't hasten you to the end, you got there on your own.
You see no difference between these two. Because there's no degrees in your definition. No understanding of scale or nuance. It's all exactly the same.
And those two ramps are both Death Spirals.
So the speed at which you arrive into a death spiral has nothing to do with it. Its the difficulty to escape what's essentially certain death basically increasing exponentially.
For example, a death save where 3 failures kill isn't a spiral. A death save where each failure gives a -2 to the next save is a spiral because failing only makes it worse.
