Your sample illustrates how some cultivars like to form one large clone on a scale. Others may form six or eight small ones, in which case, most all will survive, while still others may form a mix of a couple good size and a few small ones, in which case only the largest will survive. In the case of the later, that is because the larger ones will consume all the mother scale's resources faster and faster, the bigger they get
It looks like the mother scale is/has depleted nicely, taking on the appearance of a decomposed leaf. That's nice when it turns out that way. I've seen it happen when I've planted the scale and clone attached together where if there are enough reserves, the mother scale comes back to life and continues to nurse off the clone. I discovered this when some clones here and there, never came up and found the old mother scale, still attached, looking just like new all over again.
Note the tiny delicate hair-like roots on you clone. Aren't they cute?
Some people say to never let the clone come in contact with the plastic bag and if needed add more mix to cover---which is what I try to do when I catch it. But, believe me, with all the scale cloning I do, there have been plenty of times where I didn't catch it and I doubt it ever made any difference.
Asiatic scale clones carry the seasonal cycle of the mother bulb in memory, so clones grown from 'summer or fall' mother bulbs will require a chill cycle. Trumpets (for sure) and (I think) most OT's do not require a chill cycle.
