I find the amaryllis bulbs quite forgiving, provided it has not turned too mushy or rotten or diseased beyond redemption, so document how it recovers Jane. I love doing that too, trying out different ways to grow a plant, but within acceptable limits of course. I do have my own ongoing experiment, just growing the amaryllis bulb in clayrocks and water in a glass container. So far it works, plant is alive and it just follows springtime bloom period now.
And I have seen too at my mom's place, well, they do not really know how to grow the bulb so they have left it sitting in water, really, looks like the bulb is drowning in a glass container with lots of yucky algae growing with it, but it is by the window. Surprisingly the bulb is alive, still firm to the touch. I guess as long as it has been able to grow roots, it will fight for its life.
