Replace nodes in subnet csyj4
Motivation:
- replacing dead node 5s6r2
Calculated potential impact on subnet decentralization if replacing:
- 1 additional node would result in: (gets better) the average log2 of Nakamoto Coefficients across all features increases from 2.2683 to 2.3219
Based on the calculated potential impact, replacing 1 additional nodes to improve optimization
Note: the heuristic for node replacement relies not only on the Nakamoto coefficient but also on other factors that iteratively optimize network topology.
Due to this, Nakamoto coefficients may not directly increase in every node replacement proposal.
Code for comparing decentralization of two candidate subnet topologies is at:

Note: the information below is provided for your convenience. Please independently verify the decentralization changes rather than relying solely on this summary.
Here is an explaination of how decentralization is currently calculated,
and there are also instructions for performing what-if analysis if you are wondering if another node would have improved decentralization more.
Decentralization Nakamoto coefficient changes for subnet csyj4-zmann-ys6ge-3kzi6-onexi-obayx-2fvak-zersm-euci4-6pslt-lae:
node_provider: 5.00 -> 5.00 (+0%)
data_center: 5.00 -> 5.00 (+0%)
data_center_owner: 5.00 -> 5.00 (+0%)
area: 5.00 -> 5.00 (+0%)
country: 4.00 -> 5.00 (+25%)
Mean Nakamoto comparison: 4.83 → 5.00 (+3%)
Overall replacement impact: (gets better) the average log2 of Nakamoto Coefficients across all features increases from 2.2683 to 2.3219
