I am trying to properly size the use of the Dialog Module hash for our implementation using:

modparam("dialog", "hash_size", <number that is power of two>)

However, in my testing, I have been unable to figure out the relationship between the hash size and a number of dialogs I need to support.  I think the hash size is specifying a memory block in kB, but even setting the hash size to a very tiny number does stop me from creating hundreds of dialogs.

Is there a way to determine a relationship between the hash size and a rough number of dialogs that would be expected?

An example of a a dialog looks like this from kamctl:
