There are 1/4 chances in round 2, returning results,without continue calculating the data behind,
Discarding some nones will result in hundreds of performance gains
You can stop calculating on level 3 (level 2 return result) but question why? neighbour recursions have same 1/4 chance to find full computed nonce.
That mean If you stop calculating you just lost partially computed nonce.
That is the behavior that I noticed with the TN 5 v2 and v1.
Data gets deleted and nodes get blacklisted. "Valid" nodes are able to recover the correct data (verify the safe boxes?) and send it to other "valid" nodes.
So some clients I have seen lose calculations on the network. Fair distribution.
