Changing one component of your pot call design changes everything else.
I say often "everything effects everything".
It sounds like you are at the point in this where your besr bet is to make one single change to a pot, and one single change to the next and next and next. That way you find your own go-to design. There are so many options because many work. But are you trying for a 7 out of 10 pot, or a 9.5?
If you leave holes in your pedistal, it allows sound to bounce around in the call more, and then linger to escape other places. I think along the lines of my sound shooting bouncy balls through the striking surface, and then bouncing all over trying to escape the pot, while some percentage is caught by the pot.
It is a misconception that larger holes in the bottom of the pot will make louder and more crisp turky sounds. Nope, doesn't work that way. This part of the puzzle alone boggles the mind. Now start adding and deleting extra holes within the pot. Crazy things can happen.
