Not n^Log(n), n x S^Log(n), or more easy to reason n X S^Log10(n).

The main fairness component in a n x S^Log(n) curve comes from the fact that it works the same way with the same relative price for undesired behavior at every scale.

For example if we choose a 10 base for the logarithm with S=1.05, the price of braking up your stake into 100 puppet account will be a reduction of influence to 1.05^-2 or 90.7% regardless of your stake size prior to brake up.

Braking up a whale sized stake into 100 dolphin accounts will come at a 9.3% cut in single vote influence as would braking up an orca size account into 100 minnow sized accounts or a different login account into 100 red fish sized accounts.
