opened on Jul 3, 2019

I started a 30 node network, uploaded 100MB to node 0, and tried to download the content from node 24.

It appears that 1/2 of all chunks were found on node 24, because it is in the 0 bin of node 0.
The other 1/2 were all delivered again through node 0, and a small amount from a different node.
