2. On the other hand, if the corm is big (at least 6+ inches), I will let it rot all it wants till it stops. From this point, a new growth or two will come up. Again, I will let it be on the dry-ish side.

This crash out situation till rebound may take anything from a minimum of 6 weeks to 12 weeks. Al the best.
