That's my layman's model.

> I’d love to understand the interaction effects between 1) acceleration toward singularity (prob approaching c?), 2) gravity (prob approaching infinity?), 3) distance compression experienced by infalling observer.
None of these things are useful in the case under discussion. 1) is invalid--the singularity is a moment of time, not a place in space, and you aren't "accelerating towards" it. 2) is not well-defined inside the horizon (spacetime curvature is, and does increase without bound as you approach the singularity, but that's not quite the same as "gravity"). 3) is a special relativistic effect on others observing you; you yourself don't experience any "distance compression" regardless of your state of motion.
My instinct is that the observer would subjectively experience it to take exactly the time predicted by classical mechanics to “hit” the singularity — basically that all the considerations above would cancel out in the local reference frame — but that to an outside observer it would take an infinite amount of time.
