As per @ivan request here is the pattern and the method i used to place the markers in my manual clay turntable
Mine is one similar to these https://ebay.us/B1fQuK but with a custom metal stand and long axis
I started with a spiral and conter spiral of 1 (ones)
Then i go spinning around starting with a pattern of 1, 2, 3, then 1|1, 1|2, 1|3 , 1|4 … and then I adapt as i go trying to keep the clusters as a clear and unique shape as possible.
I also have the pattern on the side you can see it in this video
